Power IC Relay
General Description
The PVT412 Series Photovoltaic Relay is a singlepole, nor mally 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 r adiation 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 through-hole or
surface mount (‘gull-wing’) terminals. It is available
in standard plastic shipping tubes or on tape-andreel. Please refer to part identification information
opposite.

Note: PVT412L relays will pass FCC Part 68 surge current requirements operating
into rated load or short circuit when protected from overvoltage by a transient protection device such as a 175 VRMS rated MOV placed between the tip and ring terminals of the telephone line or across the output of the relay. PVT412 relays will
pass the above FCC Part 68 requirements when overcurrent protection devices (such
as fusible resistors) are placed in series with tip and ring lines in addition to the
aforementioned overvoltage protection. Consult factory for additional information.
