Main parameters of silicon controlled rectifier — SUNMATE

Silicon Controlled Rectifier (SCR for short) is a high-power electrical component, also known as thyristor.

Its main parameters are current

1. Rated on state current (IT) is the maximum stable working current, commonly known as current. The IT of commonly used silicon controlled rectifier is generally from one ampere to tens of amperes.

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

3. Control electrode trigger current (IGT), commonly known as trigger current. The IGT of commonly used silicon controlled rectifier is generally several microamps to tens of milliamps.

4. Under the specified ambient temperature and heat dissipation conditions, the average current allowed to pass through the cathode and anode.
