Preliminary Data Sheet
Figure 3. Predicted I²t data for various number of discharge cycles. Pulses are assumed rectangular.
The device junction temperature T_J is assumed to be at 25^oC before each discharge event.
Test Circuit
l L_{SERIES(TOTAL)} is caculated using
1 / (f 2π)²C
where f = frequency of I_A when using
CCSTA14N40 for circuit set up and
calibration.

l The waveform shown is
representative of one produced using a
very low inductance circuit (<100nH) as
shown in the circuit diagram using the
I_G
CCSTA14N40 Solidtron. The supply
voltage (Vs) in this example was 4kV. I_k
peaked at 10kA and the peak gate
current Ig is 500mA.
