TPP25011数据手册电路保护的TVS-晶闸管规格书PDF

描述 Description

Dedicated to sensitive telecom equipment protection, this device can provide both voltage and current triggered protection with a very tight tolerance. The breakdown voltage can be easily programmed by using an external zener diode.
A multiple protection mode can be also performed when using several zener diodes, providing to each line interface an optimized protection level. The current limiting function is achieved with the use of a resistor between the gate and the cathode. The value of the resistor will determine the level of the desired current.

简介

TPP25011属于电路保护的TVS-晶闸管。由制造生产的TPP25011TVS - 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。
