●
This is a GO-NOGO test which allows to confirm the holding current (I ) level in a
functional test circuit.
TEST PROCEDURE
1/ Adjust the current level at the I value by short circuiting the AK of the D.U.T.
2/ Fire the D.U.T. with a surge current
3/ The D.U.T. will come back off-state within 50ms maximum.
OUT
for Bidirectional devices = Switch K is closed
for Unidirectional devices = Switch K is open
