ACS108-8SN中文资料过压保护交流开关数据手册ST规格书

描述 Description

The ACS108-8SN belongs to the AC switch range (built with A. S. D.® technology). This high performance switch can control a load of up to 0.8 A.

These devices switch include an overvoltage crowbar structure to absorb the inductive turn-off energy, and a gate level shifter driver to separate the digital controller from the main switch. It is triggered with a negative gate current flowing out of the gate pin.

特性 Features

• Enables equipment to meet IEC 61000-4-5 surge with overvoltage crowbar technology
• High noise immunity against static dV/dt and IEC 61000-4-4 burst
• Needs no external protection snubber or varistor
• Reduces component count by up to 80% and Interfaces directly with the micro-controller
• Common package tab connection supports connection of several alternating current switches on the same cooling pad
• VCL gives headroom before clamping then crowbar action

简介

ACS108-8SN属于分立半导体产品的晶闸管-TRIAC。由制造生产的ACS108-8SN晶闸管 - TRIAC晶闸管可沿一个方向或在半个 AC 周期内传导 AC（交流电）。当 TRIAC（三极管 AC）的门极被触发时，即会沿任一方向传导电流。其他名称包括双向三极晶闸管或双侧三极晶闸管。TRIAC 分为无缓冲器、Alternistor、内部触发、逻辑门和标准型，安装方式包括底座、表面或通孔安装。这些器件可根据断态电压、通态电流、保持电流和门极触发电压进行选择。
