NOTES: A. The VGG amplitude and RG are adjusted for di/dt = 20 A/µs. A VGG double-pulse train is used to set IF = 0.35 A, where t1 = 10 µs,

t2 = 7 µs, and t3 = 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.

C. IRM = maximum recovery current

† Non JEDEC symbol for avalanche time.

NOTES: A. The word generator has the following characteristics: tr ≤ 10 ns, tf ≤ 10 ns, ZO = 50 Ω.

B. Input pulse duration, tw, is increased until peak current IAS = 600 mA.

Energy test level is defined as EAS = (IAS × V(BR)DSX × tav)/2 = 75 mJ.
