data sheet no. pd10044-e series pvt322a microelectronic power ic hexfet ? power mosfet photovoltaic relay dual pole, normally open 0-250v, 170ma ac/dc (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 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 pvt322a relays are packaged in an 8-pin, molded dip package with either thru-hole or sur- face mount (gull-wing) terminals. it is available in standard plastic shipping tubes or on tape-and-reel. please refer to part identification information oppo- site. features hexfet power mosfet output bounce-free operation 4,000 v rms i/o isolation linear ac/dc operation solid-state reliability applications on/off hook switch tip and ring line switching general switching part identification pvt322a thru-hole pvt322as smt PVT322AS-T smt, t&r
