ACS108-8SUN中文资料Overvoltage protected AC switch数据手册ST规格书

描述 Description

The ACS108-8SUN belongs to the AC line switch range (built with A.S.D.®technology).This high performance switch can control a load of up to 0.8 A.
The ACS108-8SUN switch includes an overvoltage crowbar structure to absorb the overvoltage 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

• Less footprint area than SOT-223 (saves PCB)
• ECOPACK®2 compliant component
• Thinner option versus SOT-223 (1.1 mm max. thickness)
• Enables equipment to meet IEC 61000-4-5
• High noise immunity against static dV/dt and IEC 61000-4-4 burst
• Overvoltage protection by crowbar technology
• Needs no external protection snubber or varistor
• Reduces component count by up to 80% and Interfaces directly with the micro-controller
• VCLgives headroom before clamping then crowbar action
• Common package tab connection supports connection of several alternating current switches on the same cooling pad

简介

ACS108-8SUN属于分立半导体产品的晶闸管-TRIAC。由制造生产的ACS108-8SUN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。
