NOTES: A. The V
GG
amplitude and R
G
are adjusted for di/dt = 20 A/µs. A V
GG
double-pulse train is used to set I
F
= 0.35 A, where t
1
= 10 µs,
t
2
= 7 µs, and t
3
= 3 µs.
B. 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.
