The rated average current (A) is the maximum repetition average forward current that can pass through the SCR, and it is 1650.RMS current describes the current's average strength, regardless of its direction, and it has RMS current (Irms) of 3.08 kA.An electrical, electromagnetic, or electronic device's holding current (hypostatic) is defined as the minimum current needed for it to remain in the 'ON' state.When the device is operating normally, the peak on-state voltage (V) should equal 1.73@4000A.SCRs are rated for surge current for a limited period during their life span, and their surge current rating is 32000.This is the voltage of the repetitive peak reverse voltage, which includes all repetitive transients.
