SP540-X Datasheet | Solid State Optronic

1 Form A Solid State Relay DESCRIPTION .. The SP540-X is a single-pole, single-throw, normally open multipurpose DC solid-state relay designed to replace electromechanical relays in critical applications requiring fast switching and solid state reliability. It is posed of an Al Ga As 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. A 300 ohm input resistor in series with the LED eliminates the need for a discrete resistor to be provided in application circuit, allowing the SP540-X to be activated by most mon logic level signals.
