A.

The VGG amplitude and RG are adjusted for di/dt = 20A/µs. A VGG double-pulse train is used to set IF = 0.35A, where t1= 10µs, t2 = 7µs,

and t3 = 3µs.

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.

B.

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

C.

Input pulse duration, tw, is increased until peak current IAS = 600mA. Energy test level is defined as EAS = (IAS x V(BR)DSX x tav)/2 =

75mJ.
