Description

The ACST12 series belongs to the ACS/ACST family built with the ASD (application specific discrete) technology. This high performance device is adapted to home appliances or industrial systems and drives loads up to 12 A.

Features

■ Triac with overvoltage crowbar technology

■ Low IGT (<10 mA) or high immunity (IGT<35 mA) version

■ High noise immunity: static dV/dt > 2000 V/μs

Benefits

■ Enables equipment to meet IEC 61000-4-5

■ High off-state reliability with planar technology

■ Need no external over voltage protection

■ Reduces the power passive component count

■ High immunity against fast transients described in IEC 61000-4-4 standards

Applications

■ AC mains static switching in appliance and industrial control systems

■ Drive of medium power AC loads like:

– Universal drum motor of washing machine

– Compressor for fridge or air conditioner

ACST12-7CT屬于分立半導體產(chǎn)品 > 晶閘管 - TRIAC。意法半導體（ST）集團制造生產(chǎn)的ACST12-7CT晶閘管 - TRIAC晶閘管可沿一個方向或在半個 AC 周期內(nèi)傳導 AC（交流電）。當 TRIAC（三極管 AC）的門極被觸發(fā)時，即會沿任一方向傳導電流。其他名稱包括雙向三極晶閘管或雙側(cè)三極晶閘管。TRIAC 分為無緩沖器、Alternistor、內(nèi)部觸發(fā)、邏輯門和標準型，安裝方式包括底座、表面或通孔安裝。這些器件可根據(jù)斷態(tài)電壓、通態(tài)電流、保持電流和門極觸發(fā)電壓進行選擇。
