parameter.
This is a GO-NOGO Test which allows to confirm the holding current (I
H
) level in a functional
test circuit.
TEST PROCEDURE :
1) Adjust the current level at the I
H
value by short circuiting the AK of the D.U.T.
2) Fire the D.U.T with a surge Current : Ipp = 10A , 10/1000
s.
3) The D.U.T will come back off-state within 50 ms max.
