Microelectronic
Power IC Relay
Single Pole, Normally Open, 0-250V, 190mA AC/DC
General Description
The PVT312 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.
This SSR is specifically designed for telecom
applications. PVT312L employs an active current-
limiting circuitry enabling it to withstand current
surge transients.
PVT312 Relays are packaged in a 6-pin, molded
DIP package with either through-hole or surface
mount ( “gull-wing”) terminals. It is available in
standard plastic shipping tubes or on tape-and-reel.
