Data Sheet No. PD 10038 revL

Series PVT312PbF

Microelectronic Power IC

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

General Description

The PVT312 Photovoltaic Relay is a single-pole,

normally 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 applica-

tions. PVT312L employs an active current-limiting cir-

cuitry 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.
