Series PVT412PbF
Microelectronic Power IC
HEXFET® Power MOSFET Photovoltaic Relay
Single-Pole, Normally-Open, 0-400V, 140mA AC/DC General Description Features The PVT412 Series Photovoltaic Relay is a singlepole, normally open solid-state relay that can replace
electromechanical relays in many applications. It
utilizes 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
radiation from a GaAlAs light emitting diode (LED)
which is optically isolated from the photovoltaic
generator.
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
requirements when overvoltage protection is
provided. PVT412 does not employ the currentlimiting 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
standard plastic shipping tubes or on tape-and-reel.
