They are available in SMA, SMB and DO-15 packages. ## **Benefits** Trisils are not subject to ageing and provide a fail safe mode in short circuit for a better protection. They are used to help equipment to meet various standards such as UL1950, IEC950 / CSA C22.2, UL1459 and FCC part 68. Trisils have UL94 V0 approved resin. SMA and SMB packages are JEDEC registered (DO-214AC and DO-214AA). ## **Order codes** |**Part Number**|**Marking**| |---|---| |SMP50-xxx|See_Ordering Information_

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 > 200V ➔ VOUT = 250 VRMS, R1 = 140Ω
● Device with VBO ≥ 200V ➔ VOUT = 480 VRMS, R2 = 240Ω

This is a GO-NOGO test which allows to confirm the 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. with a surge current ➔ IPP = 10A, 10/1000µs.
3/ The D.U.T. will come back off-state within 50ms maximum.
