Series PVT422
Microelectronic Power IC
HEXFET
Power MOSFET Photovoltaic Relay
Dual Pole, Normally Open
0-400V, 120mA AC/DC
General Description
The PVT422 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 PVT422 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 oppo-
