TPN3021 is a low capacitance transient surge arrestor designed for protection of high debit rate communication network. It has been designed for T1/E1 and Ethernet networks.
The TPN3021 is an application‑specific discrete device that provides tripolar overvoltage protection for high‑speed communication networks such as T1/E1 and Ethernet. It offers low capacitance to avoid signal distortion, a low holding current of 30 mA, and a peak surge capability of up to 200 A.
The datasheet lists electrical parameters, absolute ratings, thermal resistances, compliance with standards (GR‑1089 Core, ITU‑T‑K20/K21, VDE0433, VDE0878, IEC61000‑4‑2), and mechanical data for the SO‑8 plastic package, along with ordering information for tape‑and‑reel or tube formats.
