TEST PROCEDURE
Pulse test duration (tp = 20ms):
● for Bidirectional devices = Switch K is closed
● for Unidirectional devices = Switch K is open
VOUT selection:
● Device with VBO < 200V ➔ VOUT = 250 VRMS, R1 = 140Ω
● Device with VBO ≥ 200V ➔ VOUT = 480 VRMS, R2 = 240Ω

D.U.T
Surge
generator
This is a GO-NOGO test which allows to confirm the holding current (IH) level in a
functional test circuit.
TEST PROCEDURE
1/ Adjust the current level at the IH value by short circuiting the AK of the D.U.T.
2/ Fire the D.U.T. with a surge current ➔ IPP = 10A, 10/1000µs.
3/ The D.U.T. will come back off-state within 50ms maximum.
