Transient Voltage Suppressors
1KSMBJ series
1000W SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR
The 1KSMBJ range of surface mount protectors utilises the proven glass passivated technology used in
many of Littelfuse products portfolio. Rated at 1000 watts (10 x 1000 µs double exponential
waveform), the 1KSMBJ bridges the gap left by traditional types rated at 600 watts and 1500 watts,
suiting many applications where both power handling and size are paramount. The extremely fast
turn-on time, (less than one pico second), coupled with the low clamping factor and low on-state
impedance make this range ideal for the protection of today’s circuits. Our specially selected range of
voltages has been chosen to fulfill optimum protection for use in automotive and telecom
applications.

max
The SLDTM series is specifically designed for automotive applications, available in both
unidirectional and bidirectional.
The SLD 10U is designed to be used in series, for example three 10Us in series for a 30
volt working; this configuration will provide a very high power (a multiple of 3)
capability and is a far superior solution than using devices in parallel, which will require
closely matched devices in order to prevent ‘current hogging’ and consequently,
damage to the device.

AK10 range
The new AK10 series of high current transient suppressors have been
specially designed for use in A.C. Line Protection and any demanding
applications (AC or DC).They offer superior clamping characteristics over
standard S.A.D. technologies by virtue of the Littelfuse Foldbak™ technology, which provides a clamping voltage which is lower than the avalanche
voltage (but above the rated working voltage) therefore any voltage rise
due to increased current conduction is contained to a minimum, providing
the best possible protection level. They can also be connected in series
and/or parallel to create very high capacity protection solutions.

AK6 range
The new AK6 series of high current transient suppressors have been specially designed for use in A.C. Line Protection and any demanding applications (AC or DC).They offer superior clamping characteristics over standard
S.A.D. technologies by virtue of the Littelfuse Foldbak™ technology, which
provides a clamping voltage which is lower than the avalanche voltage (but
above the rated working voltage) therefore any voltage rise due to increased
current conduction is contained to a minimum, providing the best possible
protection level. They can also be connected in series and/or parallel to create very high capacity protection solutions.

TELECOMMUNICATIONS TRANSIENT VOLTAGE SUPPRESSORS FOR
PROTECTION AGAINST INDUCED LIGHTNING CONDITIONS
Designed to protect sensitive telecommunications electronics from transients which
originate from induced lightning, power cross and inductive load switching etc.,
especially where breakover devices would cause nuisance latch-up.
Min 25.4

DESCRIPTION
The foldback characteristic of this device eliminates the clamping of the DC current, or
the battery, used in telecom systems, so latch-up is eliminated. Latch-up can occur with
breakover devices due to the conduction follow-on current supplied by the DC system,
after the device has responded to a transient.
Min 25.4
With breakover devices, latch-up will happen more readily as the ambient temperature
rises because the holding current values will fall with rising temperature.
The Foldbak eliminates this problem whilst still providing high levels of protection.

Varistor Products
Thermally Protected
TMOV® and iTMOV® Varistor Series
The Littelfuse TMOV and iTMOV thermally protected varistors represent a
new development in integrated circuit protection (patent pending). Both
versions are comprised of radial leaded MOVs (Metal Oxide Varistors)
with an integrated thermally activated element designed to open in the
event of overheating due to the abnormal over-voltage, limited current,
conditions outlined in UL1449.
The iTMOV varistor differs from the TMOV varistor by the inclusion of a
third lead for the purpose of indicating that the MOV has been disconnected from the circuit. This lead facilitates connection to monitoring circuitry.
The TMOV and iTMOV varistors offer quick thermal response due to the
close proximity of the integrated thermal element to the MOV body. The
integrated configuration also offers lower inductance than most discrete
solutions resulting in improved clamping performance to fast over-voltage
transients. Additionally, TMOV and iTMOV varistors are wave solderable,
thus simplifying end product assembly by reducing the expense and
rework associated with hand soldering operations.
The TMOV and iTMOV varistors are both recognized surge suppression
components to UL 1449. The TMOV and iTMOV varistor’s integrated
thermal element, in conjunction with appropriate enclosure design, helps
facilitate TVSS module compliance to UL1449 for both cord connected
and permanently connected applications.
TMOV and iTMOV varistors are compatible for use with industry standard
wave-soldering processes or recommended hand-soldering methods.

iTMOV Varistor Application Examples
The application examples below show how the indicator lead on the
iTMOV can be used to indicate that the thermal element has been
opened. This signifies that the circuit is no longer protected from
transients by the MOV.

Application Example 2 (Figure 2)
Figure 1. Application example 1
This circuit utilizes an optocoupler to provide galvanic isolations
between the iTMOV varistor and the indicating or alarm circuitry.
Line Fuse
This circuit illustrates the use of the monitoring lead of the iTMOV
varistor to ensure that equipment is only operated when overvoltage
protection present. In normal operation the load switch relay solenoid is
powered via the indicator lead of the iTMOV varistor. In the event of the
thermal element being activated, the relay will de-activate, cutting power
to the protected circuit and the fault LED will illuminate.

Note : The TMOV and iTMOV varistors are intended, in conjunction with
appropriate enclosure design, to help facilitate TVSS module compliance
to UL 1449, Section 37.4 (abnormal over-voltage limited current requirements). Under these extreme abnormal over-voltage conditions, the units
will exhibit substantial heating and potential venting prior to opening.
Modules should be designed to contain this possibility. Application testing
is strongly recommended.
For applications exceeding 85ºC ambient
temperature, the peak surge current and energy
ratings must be reduced as shown in Figure 3.

Soldering Recommendations
Figure 10: Wave Solder Profile
Because the TMOV and i TMOV varistors contain a thermal protection
device, care must be taken when soldering the devices into place. Two
soldering methods are possible. Firstly, hand soldering: It is recommended to heat-sink the leads of the device. Secondly, wave-soldering: It is
critically important that all preheat stage and the solder bath temperatures are rigidly controlled. The recommended solder for the TMOV and
i TMOV varistors is a 62/36/2 (Sn/Pb/Ag), 60/40 (Sn/Pb) or 63/37(Sn/Pb).
Littelfuse also recommends an RMA solder flux.

Silicon Protection Circuits
Upstream USB Port Terminator with ESD Suppression & EMI Filtering
SPUSB1 Series
NEW
The Littelfuse SPUSB1 Series is a multifunctional USB port protection
network designed to provide ESD protection, EMI/RFI filtering and line
termination for a single USB 1.1 port. The SPUSB1 can replace a minimum of ten typically larger “discrete” devices resulting in inventory and
placement cost savings.
The SPUSB1 Series combines Transient Voltage Suppression (TVS)
avalanche diodes, EMI/RFI filtering components (R1 and C1), and a
1.5kΩ termination resistor (R2). The filtering components are included to
satisfy recommendations in the USB 1.1 specification, and the 1.5kΩ
resistor (R2) is included as a pull-up resistor to VBUS.
The SPUSB1 Series can be used for termination and protection of
“upstream” USB devices such as PDAs, digital cameras, scanners and
hubs which are often at risk from transient voltage surges and electromagnetic interference from both internal and external sources.
To support a wide range of circuit conditions, Littelfuse offers three
resistance values for the series resistor (R1). The series resistance plus
the USB driver output resistance must be close to the USB cable’s characteristic impedance of 45Ω (90Ω balanced) to minimize transmission
line reflections.

ESD Performance Notes:
(1) ESD applied to input/outputVDD pins with respect to GND, one at a time.
Clamping Voltage is measured at the opposite side of the EMI filter to the ESD pin (ie: if ESD is applied to pin1 then clamping
voltage is measured at pin 6). Unused pins are open.
These parameters guaranteed by design.
