General Description

The ASSR-41X X S eries c onsists of an AlG aAs infrar ed light-emitting diode (LED) input stage optically coupled to a high-v oltage output det ector circuit.

The det ector consists of a high-speed phot ovoltaic diode arra y and driver circuitry to switch on/off t wo discrete high v oltage MOSFETs.

The relay turns on (c ontact closes) with a minimum input curr ent of 3mA thr ough the input LED .
