CURRENT WAVEFORM
NOTES: A. The DRAIN terminal under test is connected to the TP K test point. All other terminals are connected together and connected to the
TP A test point.
B. The V
amplitude and R are adjusted for di/dt = 20 A/µs. A V
double-pulse train is used to set I = 0.1 A, where t = 10 µs,
