Single Pole, Normally Open
0-60V AC, 1.0A
HEXFET® POWER MOSFET PHOTOVOLTAIC RELAY
General Description
The PV AZ172N Photovoltaic Relay is a singlepole, normally open solid state relay that can
replace electromechanical relays used for general purpose switching of DC and AC loads. It
utilizes International Rectifier’s HEXFET power
MOSFETs as the output switches, driven by an
integrated circuit photovoltaic generator of novel
construction. The output switch is controlled by
radiation from a GaAlAs light emitting diode
(LED) which is optically isolated from the
photovoltaic generator.
These units overcome the limitations of both
electromechanical and reed relays by offering
the solid-state advantages of high sensitivity,
miniaturization, no contact bounce, long operational life, insensitivity to external magnetic fields,
shock and vibration, and high reliability inherent
with solid state technology. They are ideally
suited for switching high currents or low level
signals without distortion or injection of electrical noise.
These relays are packaged in 8-pin, molded
DIP packages and available with thru-hole and
SMT (gull-wing) leads, in plastic shipping tubes.
