BTW691200 Thyristor SCR 1200V 50A TO-3P

From the shop's description

BTW691200 Thyristor SCR 1200V 50A TO-3P The BTW69-1200 is a rugged silicon thyristor (SCR) designed for heavy-duty power switching. Housed in a high-power package (TO-3P) with excellent thermal dissipation, it withstands high repetitive off-state voltages and handles large continuous and surge on-state currents. The device is built for applications where reliable, high-energy switching and strong surge capability are required its clip-assembly construction and ceramic insulation provide high surge robustness and high isolation. Deployments include solid-state relays, welding equipment, motor controls and other power conversion systems. Features: High-power SCR (thyristor) construction. Robust surge/current-handling clip assembly. High voltage insulation with ceramic pad. Good thermal dissipation in power package. Reliable repeated switching performance. Designed for heavy industrial duty and long life.
