Vishay, LH1525AAB DC Input MOSFET Output Optocoupler, Surface Mount, 6-Pin SMD

The Vishay 1 form A solid state relay is SPST normally open switch (1 Form A) that can replace electromechanical relays in many applications. The relay requires a minimal amount of LED drive current to operate, making it ideal for battery powered and power consumption sensitive applications. The relay is constructed using a GaAIAs LED for actuation control and MOSFETs for the switching output. The relay employs current-limiting circuitry and can be configured for AC/DC or DC-only operation.

It is compliant to RoHS directive and lead free
It requires low operating current and provides high speed operation
