SMP50数据手册电路保护的TVS-晶闸管规格书PDF

描述 Description

These Trisil series have been designed to protect telecommunication equipment against lightning and transient induced by AC power lines.

They are available in SMA, SMB and DO-15 packages.

特性 Features

• Repetitive peak pulse current :IPP = 50 A (10/1000μs)
• Bidirectional crowbar protection
• Low capacitance from 12pF to 20pF @ 50V
• Voltage range from 62V to 270V
• Holding current: IH = 150 mA min
• Low leakage current : IR = 2μA max

简介

SMP50属于电路保护的TVS-晶闸管。由制造生产的SMP50TVS - 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。
