BOSFET® Photovoltaic Relay
Dual-Pole, 180mA, 0-300V AC/DC
The PVR33 Photovoltaic Relay is a dual-pole, normally
open solid state replacement for electro-mechanical
relays. It utilizes as an output switch a unique
BOSFET Power IC n
1010 Operations n
bidirectional (AC or DC) MOSFET power IC termed
100µsec Operating Time n
a BOSFET.The BOSFET is controlled by a photovoltaic
0.2µVolt Thermal Offset n
generator of novel construction, which is energized
by radiation from a dielectrically isolated light
5 milliwatts Pick-Up Power n
emitting diode (LED).
The PVR overcomes the limitations of reed relays by
offering the solid state advantages of long life, high
operating speed, low pick-up power, bounce-free
OBSOLETEoperation, 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 PVR can switch analog signals from thermo-
1000V/µsec dv/dt n
16-pin DIP Package n
-40°C to 85°C n
couple level to 300 volts peak AC or DC polarity.
Signal frequencies into the RF range are easily con-
trolled and switching rates up to 5kHz are achiev-
able. The extremely small thermally generated offset
voltages allow increased measurement accuracies.
Unique silicon technology developed by International
Rectifier forms the heart of the PVR. 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
PVR microelectronic power IC relay.
