General Description
The PVDZ172N Photovoltaic Relay is a single-pole,
normally open solid state relay that can replace
electromechanical relays used for general purpose
switching of DC loads. It utilizes International
Rectifier’s HEXFET power MOSFET as the output
switch, 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 surface-
mount (gull-wing) leads, in plastic shipping tubes.
