Pulse Test duration (tp = 20ms):

- For Bidirectional devices = Sw itchK is closed

- For Unidirectional devices = Sw itch K is open.

VOUT Selection

- Device w ith VBO < 200 Volt

- VOUT = 250 VRMS, R1 = 140 Ω.

- Device w ith VBO 200 Volt

- VOUT = 480 VRMS, R2 = 240Ω.

Surge generator

This is a GO-NOGOTest w hich allow s to confirmthe 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 w ith a surge current : Ipp = 10A , 10/1000 ms.

3) The D.U.T w ill come back off-state w ithin 50ms max.
