Series PVT422PbF

Microelectronic Power IC

Dual Pole, Normally Open

0-400V, 120mA AC/DC

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 util-

izes 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.
