SP540
1 Form A
Solid State Relay
DESCRIPTION
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.
