S742

www.DataSheet4U.com S742 1 Form A Solid State Relay DESCRIPTION The S742 is a bi-directional, single-pole, single-throw, normally open multipurpose relay. The circuit is composed of one LED on the input side which activates an optically coupled IC on the output - controlling the firing angle of two back-to-back SCRs. This circuit assures no false triggering under most adverse conditions, and a tight zero-volt window not exceeding 5V. FEATURES APPLICATIONS Zero-Volt Cross Switching High transient immunity 600V blocking voltage 1.2A maximum continuous current Low input control current High input-to-output isolation Solid state reliability Valve control Solenoids Home appliances Metering equipment Heating elements Gas pump control circuitry OPTIONS/SUFFIXES* ABSOLUTE MAXIMUM RATINGS* PARAMETER UNIT °C MIN -55 -40 TYP MAX 125 85 40 400 6 1.2 -H -S -TR High Output Isolation Surface Mount Option Tape and Reel www.DataSheet4U.com Storage Temperature Operating Temperature Continuous Input Current Transient Input Current Reverse Input Control Voltage Output Power Dissipation °C mA mA V W NOTE: Suffixes listed above are not included in marking on device for part number identification.
