PVT422P
Microelectronic Power IC
HEXFET
Power MOSFET Photovoltaic Relay
Dual Pole, Normally Open
0-400V, 120mA AC/DC
(HEXFET is the registered trademark for International Rectifier Power MOSFETs)
General Description
The PVT422P 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.
PVT422P is ideally suited for PCMCIA card applica-
tions. 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' sur-
face mount terminals. It is available in plastic ship-
ping tubes or on tape-and-reel. Please refer to Part
Identification (opposite) for details.
