Microelectronic Power IC

HEXFET® 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 emit­

ting diode (LED) which is optically isolated from the

photovol­taic generator.

These units overcome the limitations of both electro-

mechanical 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 pack-

ages and available with either thru-hole or surface-

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