VR = 50 V bias, VRMS = 1 V, F = 1 MHz

VR = 2 V bias, VRMS = 1 V, F = 1 MHz

This is a GO-NO GO test which confirms the holding current (IH) level in a functional test circuit.

TEST PROCEDURE :

– Adjust the current level at the IH value by short circuiting the D.U.T.

– Fire the D.U.T. with a surge current : IPP = 10 A, 10/1000 µs.

– The D.U.T. will come back to the off-state within a duration of 50 ms max.

VBAT = - 100V
