General Description
The PVT322A Series Photovoltaic Relay is a dualpole, 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 through-hole or
surface mount (gull-wing) terminals. It is available
in standard plastic shipping tubes or on tape-andreel. Please refer to Part Identification information
opposite.
