The T133-320-28 from Proton-Electrotex JSC is a Phase Control Thyristor that is suitable for use in AC/DC circuits operating as per industry standards or at higher frequencies. It has a break-over voltage of up to 2800 V and a break-over current of less than 457 A (average). This thyristor has a gate trigger voltage of up to 2.5 V and a gate trigger current of less than 250 mA. It can control high loads with a low control signal applied to the control gate while ensuring low static and dynamic 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 60 x 20 mm and is ideal for traction and industrial applications.
