General Description

The PVT422 Series Photovoltaic Relay is a dual-

pole, normally open solid-state relay that can replace

electromechanical relays in many applications. It

utilizes International Rectifier’s 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.

Series PVT422 Relays are packaged in an 8-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 Part Identification information opposite.
