General Description

The PVT312 Photovoltaic Relay is a single-pole,

normally open solid-state relay that can replace

electromechanical relays in many applications. It

utilizes 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

applications. PVT312L employs an active current-

limiting circuitry enabling it to withstand current surge

transients.

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

plastic shipping tubes or on tape-and-reel. Please

refer to the Part Identification information opposite.
