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. FEATURES APPLICATIONS • High Continuous Load Current Rating (750mA) • Reed relay replacement • Low On-resistance (2 ohms MAX) • Meter reading systems • Low Input Control power consumption (2.5mA TYP) • Medical equipment • 300 ohm input resistor (in series with input LED) • Battery monitoring • High input-to-output isolation • Multiplexers • Long life/high reliability OPTIONS/SUFFIXES* • -H High Output Isolation • -TR Tape and Reel NOTE: Suffixes listed above are not included in marking on device for part number identification.
