Data Sheet No. PD 10038-F

Series PVT312

Microelectronic Power IC

Single Pole, Normally Open, 0-250V, 190mA AC/DC

General Description

The PVT312 Photovoltaic Relay is a single-pole, nor-

mally open solid-state relay that can replace

electromechanical relays in many applications. It util-

izes International Rectifier’s proprietary HEXFET

power MOSFET as the output switch, 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.

This SSR is specifically designed for telecom appli-

cations. PVT312L employs an active current-limiting

circuitry enabling it to withstand current surge tran-

sients.

PVT312 Relays are packaged in a 6-pin, molded

DIP package with either thru-hole or surface mount

( “gull-wing”) terminals. It is available in standard plas-

tic shipping tubes or on tape-and-reel. Please refer

to the Part Identification information opposite.
