Series PVT322A
HEXFET POWER MOSFET PHOTOVOLTAIC RELAY
®
Microelectronic
Power IC Relay
Dual Pole, Normally Open
0-250V, 170mA AC/DC
General Description
The PVT322A Series Photovoltaic Relay is a dual-
pole, normally open solid-state relay that can
replace electromechanical relays in many applica-
tions. It utilizes International Rectifier’s 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.
Series PVT322A Relays are packaged in an 8-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. Please refer to Part Identification information
opposite.
