Description

The ACST2 series 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 loads up to 2 A.

Main features

■ Overvoltage crowbar technology

■ High noise immunity: static dV/dt > 500 V/μs

The ACST2-8SFP in the TO-220FPAB package provides insulation voltage rated at 1500VRMS

Main application

■ AC ON/OFF static switching in appliances & industrial control systems

■ Drive of low power highlyresistive or inductive loads like:

– solenoid,

– pump, fan, micro-motor

Benefits

■ Enables equipment to meet IEC 61000-4-5

■ High off-state reliability with planar technology

■ Needs no external overvoltage protection

■ Reduces component count

■ Interfaces directly with the micro-controller

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

ACST2-8SB屬于分立半導(dǎo)體產(chǎn)品 > 晶閘管 - TRIAC。意法半導(dǎo)體（ST）集團(tuán)制造生產(chǎn)的ACST2-8SB晶閘管 - TRIAC晶閘管可沿一個(gè)方向或在半個(gè) AC 周期內(nèi)傳導(dǎo) AC（交流電）。當(dāng) TRIAC（三極管 AC）的門極被觸發(fā)時(shí)，即會(huì)沿任一方向傳導(dǎo)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(biāo)準(zhǔn)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(jìn)行選擇。
