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 elec-
tromechanical relays used for general purpose switch-
ing of DC and AC loads. It utilizes International Rectifier鈥檚
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 gen-
erator.
These units overcome the limitations of both electro-
mechanical and reed relays by offering the solid-state
advantages of high sensitivity, miniaturization, no con-
tact bounce, long operational life, insensitivity to exter-
nal magnetic fields, shock and vibration, and high reli-
ability 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 pack-
ages and available with either through-hole or surface-
mount (鈥済ull-wing鈥? leads, in plastic shipping tubes.
