SP540

1 Form A

Solid State Relay

The SP540 is a single-pole, single-throw, normally open multipurpose DC solid-state relay and is designed to replace electromechanical

relays in critical applications that require fast switching and solid state reliability. It is composed of an AlGaAs LED optically coupled to a

Photo Diode Array that drives an Low On-resistance Enhancement Type DMOS transistor on the output, providing a high load current

rating.
