TPN3021 Tripolar overvoltage protection for network interfaces Features ■ ■ ■ ■ Triple crowbar protection Low capacitance Low holding current: IH = 30 mA minimum Surge current: – IPP = 200 A, 2/10 µs – IPP = 30 A, 10/1000 µs Main applications Dedicated to data line protection, this device provides a tripolar protection function. It ensures the same protection capability with the same breakdown voltage in both common and differential modes. SO-8 Description The TPN3021 is a low capacitance transient surge arrestor designed for protection of high debit rate communication network. Its low capacitance avoids distorsion of the signal as it has been designed for T1/E1 and Ethernet networks. Schematic diagram Rx+ / Tx+ 1 8 NC Benefits Trisil technology is not subject to ageing and provides a fail safe mode in short circuit for a better protection. They are used to help equipment to meet main standards such as UL1950, IEC950 / CSA C22.2 and UL1459. They have UL94 V0 ap-proved resin. SO8 package is JEDEC registered. Trisils comply with the following standards GR1089 Core, ITU-T-K20/K21, VDE0433, VDE0878, IEC61000-4-2.
