(HEXFET is the registered trademark for International Rectifier Power MOSFETs)
General Description
The PVT322A 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 PVT322A 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.
