S108 Datasheet, PDF (1/8 Pages) Solid State Optronic – Zero-Volt Cross Switching
S108
Zero Cross
700V / 0.8A
AC Solid State Relay
Description
The S108 is a bi-directional, single-pole, single-throw,
normally open multipurpose solid-state relay. The circuit is
composed of one input IR LED which activates an optically
coupled IC on the output that controls the firing angle of
two back-to-back SCRs. This circuit assures no false
triggering under most adverse conditions, and a tight zero-
volt switching window not exceeding 5V. The S108
provides high peak load voltage (700V+) and high input-to-
output isolation voltage (up to 5kVRMS).
The S108 comes in a compact 6 pin DIP package, making
it ideal for high-density board applications.
