High-Temperature Thyristor TRIACs

Littelfuse High-Temperature Thyristor TRIACs enable easier thermal management and higher surge handling capability in AC power control applications. These Littelfuse thyristors are available in 12A, 16A, 25A, 30A, and 40A variants based on their RMS on-state current, gate trigger current, and other features. Typical applications include heater control, motor speed control, lighting control, and switching relays.
