TPA SERIES ® FEATURES n BIDIRECTIONAL CROWBAR PROTECTION. n VOLTAGE RANGE: FROM 62 V TO 270 V. n HOLDING CURRENT : IH = 150mA min. n REPETITIVE PEAK PULSE CURRENT : IPP = 50 A, 10/1000 µs. DO-15 SCHEMATIC DIAGRAM DESCRIPTION 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 DO-15 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.

TEST CIRCUIT 2 for IH parameter. R D.U.T. - VP VBAT = - 48 V Surge generator This is a GO-NOGO Test which allows to confirm the holding current (IH) level in a functional test circuit. TEST PROCEDURE : n 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 µs. 3) The D.U.T will come back off-state within 50 ms max. 3/5 TPA SERIES Fig. 1: Non repetitive surge peak on-state current versus overload duration (Tj initial=25°C).
