Power MOSFET Photovoltaic Relay
Single Pole, Normally Open,
0-400V, 140mA AC/DC
General Description
The PVT412 Series Photovoltaic Relay is a single-
pole, normally open solid-state relay that can replace
electromechanical relays in many applications. It util-
izes International Rectifier’s proprietary HEXFET
power MOSFET as the output switch, driven by an
integrated circuit photovoltaic generator of novel
construction. The output switch is controlled by ra-
diation from a GaAlAs light emitting diode (LED)
which is optically isolated from the photovoltaic gen-
erator.
These SSRs are specifically designed for worldwide
telecom applications. PVT412L employs an active
current-limiting circuitry enabling it to pass FCC Part
68 and other regulatory agency current surge re-
quirements when overvoltage protection is provided.
PVT412 does not employ the current-limiting circuitry
and offers lower on-state resistance.
Series PVT412 Relays are packaged in a 6-lead
molded DIP package with either thru-hole or surface
mount (‘gull-wing’) terminals. It is available in stan-
dard plastic shipping tubes or on tape-and-reel.
