General Description
The PVT422P Series Photovoltaic Relay is a dual-
pole, normally open solid-state relay that can
replace electromechanical relays in many applica-
tions. 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 GaAiAs light emitting diode (LED)
which is optically isolated from the photovoltaic
generator.
PVT422P is ideally suited for PCMCIA card
applications. Its extremely low profile allows it to be
used in Type II cards whose outer shells are only
5mm thick.
Series PVT422P Relays are packaged in an 8-pin,
molded ‘Thin-Pak’ DIP package with ‘gull-wing’
surface mount terminals. It is available in plastic
shipping tubes or on tape-and-reel. Please refer to
Part Identification (opposite) for details.
