FEATURES
F126
The TPA series are TRISIL devices especially de-
signed 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 telecommuni-
cation equipment.

D.U.T.
This is a GO-NOGO Test which allows to confirm the holding current (I
H
) level in a functional
test circuit.
TEST PROCEDURE :
1) Adjust the current level at the I
H
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
s.
3) The D.U.T will come back off-state within 50 ms max.
