Basic and commonly used parameters of thyristor

The main parameters of thyristor:

Rated on state current (IT) refers to the maximum stable operating current, commonly known as current. The IT of commonly used thyristor is generally from one ampere to several tens of amperes.

Reverse repetitive peak voltage (VRRM) or off state repetitive peak voltage (VDRM), commonly known as withstand voltage. The VRRM/VDRM of commonly used controllable silicon is generally from several hundred volts to one thousand volts.

3 control pole trigger current (IGT), commonly known as trigger current. The IGT of commonly used thyristor is generally from a few microamps to tens of milliamps.
