The PVG612A 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 ra- diation from a GaAlAs light emitting diode (LED) which is optically isolated from the photovoltaic generator. These units exceed the performance capabilities of electromechanical relays in operating life, sensitiv- ity, stability of on-resistance, miniaturization, insen- sitivity to magnetic fields and ruggedess. The com- pact PVG612A is particularly suited for isolated switching of high currents from 12 to 48 Volt AC or DC power sources. Series PVG612A Relays are packaged in a 6-pin, molded DIP package with either thru-hole or surface mount (gull-wing) terminals. It is available in stan- dard plastic shipping tubes or on tape-and-reel. Please refer to Part Identification information opposite.
The PVG612A series photovoltaic relay is a single‑pole, normally open solid‑state relay that replaces electromechanical relays in many applications. It uses International Rectifier's HEXFET power MOSFET as the output switch, driven by an integrated photovoltaic generator and optically isolated LED.
The datasheet lists electrical specifications such as control current range (5.0‑25 mA), maximum continuous load currents (2.0 A A‑connection, 2.5 A B‑connection, 4.0 A C‑connection), pulsed load capabilities, on‑state resistance, isolation voltage (4 kV RMS), and thermal characteristics.
