General Description

The PVT412 Series Photovoltaic Relay is a single-

pole, 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 GaAlAs light emitting diode (LED)

which is optically isolated from the photovoltaic

generator.

These SSRs are specifically designed for worldwide

telecom 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 current-

limiting 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 tubes or on tape-and-reel.
