THBT20011数据手册电路保护的TVS-晶闸管规格书PDF

描述 Description

Dedicated to telecommunication equipment protection, these devices provide a triple bidirectional protection function.
They ensure the same protection capability with the same breakdown voltage both in longitudinal mode and transversal mode.
A particular attention has been given to the internal wire bonding. The “4-point” configuration ensures a reliable protection, eliminating overvoltages introduced by the parasitic inductances of the wiring (Ldi/dt), especially for very fast transient overvoltages.
Dynamic characteristics have been defined for several types of surges to meet the SLIC maximum ratings.

特性 Features

• bidirectional crowbar protection between TIP and GND, RING and GND and between TIP and RING
• peak pulse current:IPP= 30 A for 10/1000 μs surge
• holding current: IH= 150 mA
• Complies with Bellcore standard
• TR-NWT-001089-Core, (second level) with line series resistors:
• 10/1000 μs, 1000 V
• 2/10 μs, 2500 V (first level)
• 2/10 μs, 5000 V

简介

THBT20011属于电路保护的TVS-晶闸管。由制造生产的THBT20011TVS - 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。
