25TPS12 SCR Unidirectional Thyristor 1200V 25A TO-247
The 25TPS12 is a silicon controlled rectifier (SCR) — a unidirectional thyristor designed for power switching and controlled rectification. Once triggered via its gate terminal, it conducts current in one direction, making it ideal for phase‑control and high‑power switching circuits.
With a 1200 V voltage rating, the 25TPS12 is well suited for high‑voltage AC line and industrial power circuits, while its 25 A current rating allows it to drive medium‑ to high‑power loads such as motors, heaters and lamps.
