SP540-X
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 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. 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 common logic level signals.
