IBO
measurement
Pulse test duration (tp = 20 ms):
● For bidirectional devices switch K is closed.
● For unidirectional devices switch K is open.
VOUT selection:
● For device with VBO < 200 V, VOUT = 250 VRMS, R1 = 140 Ω.
● For device with VBO ≥ 200 V, VOUT = 480 VRMS, R2 = 240 Ω.

D.U.T
This is a go no-go test, which can confirm the holding current (IH) level.
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 50 ms maximum.
