Trigger, SCR Isolation
PT-50
Vishay Dale
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.
Industrial and commercial applications include motor speed controls, lighting
controls and heater controls.
Interchangeable. Designed for circuit board mounting using same mounting
dimensions as 11Z and PT-20 models.
