SP946 - AC Solid State Relay

General Description

The SP946 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.

Key Features

  • Zero-Volt Cross Switching.
  • High Blocking Voltage (800V MIN).
  • High Transient Immunity.
  • 1.2A Maximum Continuous Current.

SP946 Zero Cross 800V / 1.2A AC Solid State Relay Description The SP946 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 zerovolt switching window not exceeding 5V. The SP946 provides high peak load voltage (800V+) and high input-tooutput isolation voltage (up to 5kVRMS). The SP946 comes in a compact 4 pin SIP package, making it ideal for high-density board applications.
