PVAZ172N & PbF

Microelectronic Power IC

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’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 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 thru-hole or surface-

mount (“gull-wing”) leads, in plastic shipping tubes.
