Description
The HSR312 and HSR412 devices consist of a AlGaAs infrared emitting diode optically coupled to a power MOSFET detector which is driven by a photovoltaic generator. The devices are housed in a 6-pin dual-in-line package. The HSR312L and HSR412L employ an active current limit circuitry enabling the device to withstand current surge transients.

Applications
On/Off Hook Switch Replacement for Mechanical Relays Dial Out Relay Ring Injection Relay General Switching Ground Start
