when using
CCSTA14N40 for circuit set up and
calibration.
The waveform shown is representative
of one produced using the test circuit
shown where the DUT is the CCS AC
14N40 Solidtron. The C1 capacitor
voltage in this example was at 2.1kV. Ik
peaked at 4kA at 1us and the peak gate
current Ig is 1A.
