TPN3021 Tripolar overvoltage protection for network interfaces Features Triple crowbar protection Low capacitance Low holding current: I = 30 mA minimum H Surge current: I = 200 A, 2/10 s PP SO-8 I = 30 A, 10/1000 s PP Benefits Figure 1. Schematic diagram Trisil technology is not subject to ageing and provides a fail safe mode in short circuit for a better protection. Rx+ / Tx+ 1 8 NC This device can be used to help equipment to meet main standards such as UL1950, IEC 950 / CSA C22.2 and UL1459. NC 2 7 NC Trisils have UL94 V0 approved resin. SO8 package is JEDEC registered. NC 3 6 GND Trisils comply with the following standards GR-1089 Core, ITU-T-K20/K21, VDE0433, Rx- / Tx- 4 5 NC VDE0878, IEC 61000-4-2. Applications Description Dedicated to data line protection, this device provides a tripolar protection function. It ensures The TPN is a low capacitance transient surge the same protection capability with the same arrestor designed for protection of high debit rate breakdown voltage in both common and communication networks. Its low capacitance differential modes. avoids distorsion of the signal as it has been designed for T1/E1 and Ethernet networks.
