BOSFET® Photovoltaic Relay
Single-Pole, 70mA, 0-100V AC/DC
General Description
The Photovoltaic AC Relay (PVA) is a single-pole,
normally open solid state replacement for electromechanical relays used for general purpose switching of analog signals. It utilizes as an output switch a
unique bidirectional (AC or DC) MOSFET power IC
termed a BOSFET. The BOSFET is controlled by a
photovoltaic generator of novel construction, which
is energized by radiation from a dielectrically
isolated light emitting diode (LED).
The PVA overcomes the limitations of both conventional and reed electromechanical relays by offering
the solid state advantages of long life, high operating speed, low pick-up power, bounce-free operation, low thermal voltages and miniaturization. These
advantages allow product improvement and design
innovations in many applications such as process
control, multiplexing, telecommunications, automatic
test equipment and data acquisition.
The PVA can switch analog signals from thermocouple level to 100 volts peak AC or DC polarity.
Signal frequencies into the RF range are easily controlled and switching rates up to 18kHz are achievable. The extremely small thermally generated offset
voltages allow increased measurement accuracies.
Unique silicon technology developed by International
Rectifier forms the heart of the PVA. The monolithic
BOSFET contains a bidirectional N-channel power
MOSFET output structure. In addition, this power IC
chip has input circuitry for fast turn-off and gate protection functions. This section of the BOSFET chip
utilizes both bipolar and MOS technology to form
NPN transistors, P-channel MOSFETs, resistors,
diodes and capacitors.
The photovoltaic generator similarly utilizes a unique
International Rectifier alloyed multijunction structure.
The excellent current conversion efficiency of this
technique results in the very fast response of the
PVA microelectronic power IC relay.
This advanced semiconductor technology has created
a radically new control device. Designers can now
develop switching systems to new standards of electrical performance and mechanical compactness.
