TPN3021中文资料网络接口的三极过压保护数据手册ST规格书

描述 Description

The TPN is a low capacitance transient surge arrestor designed for protection of high debit rate communication networks. Its low capacitance avoids distorsion of the signal as it has been designed for T1/E1 and Ethernet networks.

特性 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
• Benefits
•Trisil™ technology is not subject to ageing and provides a fail safe mode in short circuit for a better protection.
•This device can be used to help equipment to meet main standards such as UL1950, IEC 950 / CSA C22.2 and UL1459.
•Trisils have UL94 V0 approved resin.
•SO8 package is JEDEC registered.
•Trisils comply with the following standards GR-1089 Core, ITU-T-K20/K21, VDE0433, VDE0878, IEC 61000-4-2.

简介

TPN3021属于电路保护的TVS-晶闸管。由制造生产的TPN3021TVS - 晶闸管基于晶闸管的瞬态电压抑制 (TVS) 器件可用于提供过压保护，在正常工作条件下近似于开路。在这些器件两端施加超过某个特定值的电压（称为击穿电压），可使它们进入近似于短路的导通状态。?这种状态一直持续至流过器件的电流因电路中的一些外部影响而降低到称为“保持电流”的最小值以下。
