TISP4xxxH3BJ Overview

This TISP® device series protects central office, access and customer premise equipment against overvoltages on the telecom line. The TISP4xxxH3BJ is available in a wide range of voltages and has a high current capability, allowing minimal series resistance to be used. These protectors have been specified mindful of the following standards and recommendations: GR-1089-CORE, FCC Part 68, UL1950, EN 60950, IEC 60950, ITU-T K.20, K.21 and K.45. The TISP4350H3BJ meets the FCC Part 68 “B” ringer voltage requirement and survives the Type A and B impulse tests. These devices are housed in a surface mount SMB (DO-214AA) package.

TISP4350H3BJR属于电路保护 > TVS - 晶闸管。伯恩斯（邦士）制造生产的TISP4350H3BJRTVS - 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。
