Basic common parameters of thyristors

The main parameters of the thyristor:

1 Rated on-state current (IT) is the maximum stable working current, commonly known as current. The IT of commonly used thyristors is generally one to dozens of amps.

2 Reverse repetitive peak voltage (VRRM) or off-state repetitive peak voltage (VDRM), commonly known as withstand voltage. The VRRM/VDRM of commonly used thyristors is generally a few hundred volts to a thousand volts.

3 Control pole trigger current (IGT), commonly known as trigger current. IGTs commonly used with thyristors generally range from a few microamps to tens of milliamps.
