Power MOSFET Photovoltaic Relay
Dual Pole, Normally Open
0-250V, 170mA AC/DC
Series PVT322APbF
General Description
The PVT322A Series Photovoltaic Relay is a dual-
pole, normally open solid-state relay that can replace
electromechanical relays in many applications. It util-
izes 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 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 opposite.
