Series PVT322
Microelectronic Power IC
HEXFET
Power MOSFET Photovoltaic Relay
Dual Pole, Normally Open
0-250V, 170mA AC/DC
(HEXFET is the registered trademark for International Rectifier Power MOSFETs)
General Description
The PVT322 Series Photovoltaic Relay is a dual-
pole, normally open solid-state relay that can re-
place electromechanical relays in many applications.
It utilizes International Rectifier's HEXFET power
MOSFET as the output switch, driven by an inte-
grated circuit photovoltaic generator of novel con-
struction. The output switch is controlled by radia-
tion from a GaAlAs light emitting diode (LED) which
is optically isolated from the photovoltaic generator.
Series PVT322 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.
