ACST6-7ST分立半导体产品的晶闸管-TRIAC规格书PDF中文资料

ACST6-7ST属于分立半导体产品的晶闸管-TRIAC。由意法半导体集团制造生产的ACST6-7ST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。

DESCRIPTION

The ACST6-7Sx belongs to the AC power switch family built around the ASD technology. This high performance device is adapted to home appliances or industrial systems and drives an induction motor up to 6A.

This ACST switch embeds a triac structure with a high voltage clamping device to absorb the inductive turn-off energy and withstand line transients such as those described in the IEC61000-4-5 standards.
