S742_15 Datasheet, PDF (1/5 Pages) Solid State Optronic – High transient immunity

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
• ^{Zero-Volt Cross Switching}
• ^{High transient immunity}
• ^{600V blocking voltage}
• ^{1.2A maximum continuous current}
• ^{High input-to-output isolation (3.75kV MIN)}
• ^{Solid state reliability}
• ^{RoHS / Pb-Free / REACH Compliant}
OPTIONS/SUFFIXES*
• ^{-S Surface Mount Leadform Option (25 pcs / tube)}
• ^{-TR Tape and Reel Packing Option (1,000 pcs / reel)}
NOTE: Suffixes listed above are not included in marking on
device for part number identification.
