Series PVT422PbF
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 thru-hole or surface
mount (gull-wing) termin als. It is available in standard
plastic shipping tubes or on tape-and-reel. Please refer
to Part Identification information opposite.
