data sheet no. pd 10038 revl series pvt312pbf microelectronic power ic hexfet ? power mosfet photovoltaic relay single pole, normally open, 0-250v, 190ma ac/dc general description the pvt312 photovoltaic relay is a sin gle-pole, normally open solid-state re lay that can replace electromechani cal re lays in many applications. it util - izes international rectifers proprietary hexfet power mosfet as the output switch, driven by an inte grated circuit photovoltaic gen erator of novel construction. the output switch is con trolled by radiation from a gaalas light emit ting diode (led) which is optically isolated from the photovol taic generator. this ssr is specifcally designed for tele com applica - tions. pvt312l employs an active cur rent-limiting cir - cuitry enabling it to withstand current surge transients. pvt312 relays are packaged in a 6-pin, molded dip package with either thru-hole or surface mount ( gull-wing) termi nals. it is avail able in standard plastic ship ping tubes or on tape-and-reel. please refer to the part identifca tion in formation opposite. applications ? on/off hook switch ? dial-out relay ? ring injection relay ? ground start ? general switching (hexfet is the registered trademark for international rectifer power mosfets) part identifcation pvt312lpbf current limit, thru-hole pvt312lspbf current limit, surface-mount pvt312ls-tpbf current limit,surface-mount, tape and reel pvt312pbf no current limit, thru-hole PVT312SPBF no current limit, surface- mount pvt312s-tpbf no current limit, surface- mount, tape and reel features ? hexfet power mosfet output ? bounce-free operation ? 4,000 v rms i/o isolation ? load current limiting ? linear ac/dc operation ? solid-state reliability ? ul recognized and babt certifed; ? esd tolerance: 4000v human body model 500v machine model www.irf.com 1
