TPA SERIES
BIDIRECTIONAL CROWBAR PROTECTION.
VOLTAGERANGE: FROM 62 V TO270 V.
HOLDINGCURRENT:
IH = 150mAmin.
REPETITIVEPEAK PULSECURRENT :
IPP = 50 A, 10/1000 ms.
FEATURES
F126
The TPA series are TRISIL devices especially designed
for protecting sensitive telecommunication
equipment against lightning and transient voltages
induced by AC power lines. They are available in
the F126 axial package.
TRISIL devices provide bidirectional protection
by crowbar action. Their characteristic response
to transient overvoltages makes them particularly
suited to protect voltage sensitive telecommunication
equipment.

TESTPROCEDURE :
Pulse Test duration (tp = 20ms):
- For Bidirectional devices = SwitchK is closed
- For Unidirectional devices = Switch K is open.
VOUT Selection
- Device with VBO < 200 Volt
- VOUT = 250 VRMS, R1 = 140 W.
- Device with VBO . 200 Volt
                   - VOUT = 480 VRMS, R2 = 240W.

D.U.T.
This is a GO-NOGOTest which allows to confirm the holding current (IH) level in a functional
test circuit.
TESTPROCEDURE :
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 , 10/1000 ms.
3) The D.U.T will come back off-state within 50ms max.
