Power MOSFET Photovoltaic Relay
Single-Pole, Normally-Open, 0-60V AC, 1.0A
General Description
The PVAZ172N Photovoltaic Relay is a single-pole,
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 either thru-hole or
surface-mount (“gull-wing”) leads, in plastic shipping
tubes.
