PVT412S

The PVT412S Series Photovoltaic Relay is a singlepole, normally open solid-state relay that can replace electromechanical relays in many applications. PVT412S utilizes International Rectifier's proprietary 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. These SSRs are specifically designed for worldwide telecom applications.

PVT412S employs an active current-limiting circuitry enabling it to pass FCC Part 68 and other regulatory agency current surge requirements when overvoltage protection is provided. PVT412S does not em ploy the current-limiting circuitry and offers lower on-state resistance.

Series PVT412S Relays are packaged in a 6-lead molded DIP package with either thru-hole or surface mount ('gull-wing') terminals. PVT412S is available in standard plastic shipping tubes or on tape-and-reel. Please refer to part identification information opposite
