PVT412PBF
Description
The PVT412 Series Photovoltaic Relay is a singlepole, normally open solid-state relay that can replace electromechanical relays in many applications. It 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 Ga Al As light emitting diode (LED) which is optically isolated from the photovoltaic generator.
These SSRs are specifically designed for worldwide tele applications. PVT412L 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. PVT412 does not employ the currentlimiting circuitry and offers lower on-state resistance.
Series PVT412 Relays are packaged in a 6-lead molded DIP package with either thru-hole or surface mount (‘gull-wing’) terminals. It is available in standard plastic shipping...
