TPN3021 TRIPOLAR OVERVOLTAGE PROTECTION FOR NETWORK INTERFACES Application Specific Discretes A.S.D. FEATURES TRIPLE CROWBAR PROTECTION PEAK PULSE CURRENT : IPP = 30 A, 10/1000µs VERY LOW CAPACITANCE : C = 30 pF PROTECTS HIGH-SPEED LINE DRIVERS / RECEIVERS DESCRIPTION SO8 Dedicated to dataline protection, this device provides a triple protection function. It ensures the same protection capability with the same breakdown voltage both in common mode and in differential mode. With a stand-off voltage of 28V and a very low capacitance, this device is able to protect high-speed interfaces such as T1/E1 interface.

FUNCTIONAL HOLDING CURRENT (IH) TEST CIRCUIT : GO-NO GO TEST R - VP D.U.T VBAT = - 48 V Surge generator This is a GO-NO GO test which allows to confirm the holding current (IH ) level in a functional test circuit. TEST PROCEDURE : - Adjust the current level at the IH value by short circuiting the D.U.T. - Fire the D.U.T. with a surge current : Ipp = 10A, 10/1000 µs. - The D.U.T. will come back to the off-state within a duration of 50 ms max. 2/4 TPN3021 APPLICATION CIRCUIT : T1/E1 Interface Protection +5V R11 R21 R12 TPN3021 R13 +5V R22 R23 LOGIC SIDE LINE SIDE +5V +5V R14 TPN3021 R24 DA108S1 Fig. 1 : Surge peak current versus overload duration.
