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
< 200 Volt
-VOUT = 250 VRMS,R1 = 140
Ω.
- Device with VBO
≥ 200 Volt
-VOUT = 480 VRMS,R2 = 240

Note 1:
IR measured at VR guarantees VBR >VR
Note 2:
Measured at 50 Hz (1 cycle) test circuit 1.
Note 3:
See the reference test circuit 2.
Note 4:
VR = 1V, F = 1MHz.
Note 5 :
See test circuit 3 for VBO dynamic parameters; Rp is the protection resistor located on the line card.
