PVDZ172N

Microelectronic

Power IC Relay

Single Pole, Normally Open

0-60V DC, 1.5A

General Description

The PVDZ172N Photovoltaic Relay is a single-

pole, normally open solid state relay that can

replace electromechanical relays used for gen-

eral purpose switching of DC loads. It utilizes

International Rectifier’s HEXFET power MOS-

FET as the output switch, driven by an integrated

circuit photovoltaic generator of novel construc-

tion. 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

electromechanical and reed relays by offering

the solid-state advantages of high sensitivity,

miniaturization, no contact bounce, long opera-

tional 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 electri-

cal noise.

These relays are packaged in 8-pin, molded

DIP packages and available with thru-hole and

SMT (gull-wing) leads, in plastic shipping tubes.
