General Description
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 radiation 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,
sensitivity, stability of on-resistance, miniaturization,
insensitivity to magnetic fields and ruggedess.
The compact 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 standard plastic shipping tubes or on tape-and-
reel. Please refer to Part Identification information
