SP540-X

SP540-X 1 Form A Solid State Relay DESCRIPTION www.datasheet4u.com 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) Low On-resistance (2 ohms MAX) Low Input Control power consumption (2.5mA TYP) 300 ohm input resistor (in series with input LED) High input-to-output isolation Long life/high reliability Reed relay replacement Meter reading systems Medical equipment Battery monitoring Multiplexers OPTIONS/SUFFIXES* ABSOLUTE MAXIMUM RATINGS* PARAMETER Storage Temperature Operating Temperature Continuous Input Current Transient Input Current Reverse Input Control Voltage Output Power Dissipation UNIT °C °C mA mA V W 6 1.2 MIN -55 -40 TYP MAX 120 85 40 400 -H -TR High Output Isolation Tape and Reel NOTE: Suffixes listed above are not included in marking on device for part number identification.
