ACS120中文资料过压保护交流开关数据手册ST规格书

描述 Description

The ACS120 belongs to the AC line switch family. This high performance switch circuit is able to control a load of up to 2 A.

The ACS™ switch embeds a high voltage clamping 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

• Blocking voltage: VDRM/ VRRM= +/- 700 V
• Avalanche controlled: VCLtyp. = 1100 V
• Nominal conducting current: IT(RMS)= 2 A
• Gate triggering current: IGT 500 V/μs

简介

ACS120属于分立半导体产品的晶闸管-TRIAC。由制造生产的ACS120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。
