1 Data Sheet No. PD 138 revl Series PVT312PbF Microelectronic Power IC HEXFET Power MOSFET Photovoltaic Relay Single Pole, Normally Open, -25V, 19mA 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 utilizes International Rectifier s 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 specifically designed for tele com applications. PVT312L employs an active cur rent-limiting circuitry 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.
