The T143-1250-8 from Proton-Electrotex JSC is a Phase Control Thyristor that is used to control high loads with a low control signal applied to the control gate. It has a repetitive peak voltage of up to 800 V and a mean on-state current of 1250 A. This thyristor has a gate trigger voltage of up to 3 V and a gate trigger current of over 400 A. It features low on-state and switching losses. This phase control thyristor offers high resistance to thermal and electrical cycling and supports natural or forced-air cooling mechanisms to facilitate temperature regulation. It is available in a disc package that measures 67 x 14 mm and is ideal for traction and industrial applications.
