Trigger, SCR Isolation
FEATURES
•
•
•
•
Designed for low-cost trigger source isolation in SCR power control circuits.
Small physical size and low profile provide packaging advantages.
Designed to transfer high amplitude or long duration pulses without saturation.
RoHS
Industrial and commercial applications include motor speed controls, lighting
COMPLIANT
controls and heater controls.
•
Interchangeable. Designed for circuit board mounting using same mounting dimensions as
11Z and PT-20 models.
