When to Choose PulseGuard® ESD Suppressors
• The application tolerates very little added capacitance (high speed data lines or RF circuits)
• ESD is the only transient threat
• Protection is required on data, signal, and control lines (not power supply lines)
When to Choose SPATM Silicon Protection Arrays
• The device being protected requires the lowest possible clamp voltage,
low capacitance (0.65pF – 30pF) and low leakage (0.02µA – 10µA)
• Board space is at a premium and space-savings multi-line protection is needed
• Transients other than ESD, such as EFT or lightning, must also be considered
When to Choose Multilayer Varistors (MLVs)
• Surge currents or energy beyond ESD is expected in the application (EFT, lightning)
• Looking to replace high wattage TVS Zener diodes (300W – 1500W)
• Added capacitance is desirable for EMI filtering (3pF – 6000pF)
• Power supply line or low/medium speed data and signal lines are to be protected
• The operating voltage is above silicon or PulseGuard® ESD suppressor ratings

ESD SUPPRESSION REQUIREMENTS
ABOUT THIS GUIDE
Electrostatic Discharge (ESD) is an electrical transient
that poses a serious threat to electronic circuits. The
most common cause is friction between two dissimilar
materials, causing a buildup of electric charges on their
surfaces. Typically, one of the surfaces is the human
body, and it is not uncommon for this static charge to
reach a potential as high as 15,000 volts. At 6,000 static
volts, an ESD event will be painful to a person. Lower
voltage discharges may go unnoticed, but can still cause
catastrophic damage to electronic components and circuits.
Choosing the most appropriate suppressor technology
requires a balance between equipment protection needs
and operating requirements, taking into account the
anticipated threat level. In addition to the electrical
characteristics of suppression devices, the form factor/
package style must also be considered.
The likelihood of electronic circuit damage is increasing as
integrated circuit (IC) dimensions are shrinking to nanometer
sizes. Most ICs operate at low voltages and have structures
and conductive paths that cannot survive the high currents
and voltages associated with ESD transients.
Another significant trend is the migration to higher
frequency communication devices to transmit more
information in less time. This means that ESD solutions
must not compromise stringent signal integrity
requirements at the higher data rates. Therefore, ESD
suppressors must have low internal capacitance so that
data communication signals are not distorted.
IC designers add a limited amount of ESD suppression
to their chips to help avoid damage during manufacturing
and assembly processes. However, the level of protection
that is added may not be sufficient to protect ICs and
other semiconductor devices from ESD during actual
usage. Many electronic products, especially portable
ones, are used in uncontrolled environments. Portable
devices can experience a charge buildup as they are
carried by users on their person or in a purse. This energy
can then be discharged to another device as the two are
connected, usually when a user touches I/O pins on a
cable connector. Therefore, end product designers should
consider adding ESD suppressors to their circuits.
This guide is designed to summarize some of the
comprehensive ESD solutions that Littelfuse offers, and help
designers narrow to technologies appropriate to their end
application:
• The table opposite this page summarizes general qualitative
factors of each Littelfuse technology
• Page 2 describes common ESD threats and circuit design
considerations
• Pages 3-5 present common end applications and the
particular Littelfuse ESD suppression products designed for
those applications
• Pages 6-9 present additional and more detailed product
selection and specification criteria
Additional articles on ESD suppression and current data
sheets about the products presented in this brochure can be

ESD Suppressor Product Selection Guide
ESD DAMAGE
Soft Failures
Electrical currents due to ESD can change the state of internal
logic, causing a system to latch up or behave unpredictably, or
cause corruption of a data stream. While this is temporary, it
may slow down communications, or require a system reboot in
the case of lockup.
ESD test waveform

%
Current (I) %
ESD is characterized by fast rise times and high peak voltages
and currents up to 30 amps (per IEC 61000-4-2, level 4), which
can melt silicon and conductor traces. However, ESD effects
can be more subtle. The three types of damage are:
I30
I60
30ns
60ns
Latent Defects
A component or circuit may be damaged by ESD and its
function degraded though the system will continue to
work. However, this type of defect often progresses to a
premature failure.
Catastrophic Failure
Of course, ESD can damage a component to the point where it
does not function as intended, or doesn’t work at all.
ESD SUPPRESSION AND CIRCUIT DESIGN CONSIDERATIONS
Proper use of ESD circuit protection helps prevent these
failures. Still, selection of a suppression device must
recognize that ESD has very short rise and fall times—less
than one nanosecond (1ns) in most cases. The International
Electrotechnical Commission (IEC) has developed a
specification (IEC 61000-4-2) for ESD testing that helps
determine if products are susceptible to ESD events.
Littelfuse device engineers use specifications like these to
design ESD suppressors with the speed, clamping voltage,
and residual current levels that will protect today’s sensitive
semiconductors and electronic circuitry. Many of these designs
have the low internal capacitance needed for high bandwidth
communications.
When selecting ESD suppressors, circuit designers need
to consider potential coupling paths that would allow ESD
to enter their equipment and circuits. These weak points
identify areas that should be considered for ESD suppressor
installation. Ultimately, designers need to select ESD
suppressors with characteristics appropriate for their type of
equipment, the component sensitivity, and the environment
where it will be used.

DATA PROTOCOL, APPLICATION AND PRODUCT SELECTION
The chart below shows the relationship between Data Rates
(Protocol), Applications, and Littelfuse ESD suppression
products.
The top of the chart shows the standard data protocols,
associated data rates, and example end applications that
may use the protocols, while the body of the chart shows the
applicable Littelfuse ESD suppressors for the various data
rates, protocols and applications.
The characteristic of concern here is capacitance. High
capacitance suppression devices will tend to add signal
distortion as signal frequencies increase; low capacitance
devices will maintain signal integrity at high data rates.
products. For example, a laptop computer could have RS232,
USB 2.0, video, and PS2 mouse ports, as well as others.
The RS232 and mouse ports use relatively slow data rates
and could use any Littelfuse suppressor (although higher
capacitance multi-layer or silicon parts are preferred for EMI
filtering capabilities). The appropriate protector for the video
port would depend on the data rate, and since the USB 2.0
port requires an extremely low capacitance suppression
device, PulseGuard® ESD Suppressor or SPATM Silicon
Protection Array devices should be considered.
If you require further assistance in selecting the appropriate
Littelfuse ESD suppressor for your specific circuit, please
contact your local Littelfuse products representative.
Note that an application may use several different data
protocols and could use as many different ESD suppressor

The information above is intended to help circuit designers determine which Littelfuse ESD suppressors are applicable
for given data protocols and data rates. Other key characteristics such as clamping voltage, leakage current, number of
lines of protection and ESD capabilities need to be considered, especially where there are overlaps in the recommended
Littelfuse ESD suppressor line (ex. IEEE 1284 and Ethernet). This information is detailed on the following pages.
At the upper data rate bounds of the products included above, the capacitances of the suppression device and the circuit
board need to be taken into account in order to maintain the signal integrity of the overall system.

Multilayer Varistors (MLVs)
MLVs provide board level
protection against ESD, EFT,
and other transients that
occur on power supply, data
and control lines. Single line
devices are available in
popular industry standard
formats, and for more
efficient board space usage,
four-line devices are also
available. Some MLVs also
offer low band-pass filtering
characteristics that filter high
frequency noise from the
circuit.
