ACS108-8SN屬于分立半導(dǎo)體產(chǎn)品的晶閘管-TRIAC。由意法半導(dǎo)體集團(tuán)制造生產(chǎn)的ACS108-8SN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(wú)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。

Features

? Enables equipment to meet IEC 61000-4-5 surge with overvoltage crowbar

technology

? High noise immunity against static dV/dt and IEC 61000-4-4 burst

? Needs no external protection snubber or varistor

? Reduces component count by up to 80 and Interfaces directly with the microcontroller

? Common package tab connection supports connection of several alternating

current switches on the same cooling pad

? VCL gives headroom before clamping then crowbar action

Description

The ACS108-8SN belongs to the AC switch range (built with A. S. D.? technology).

This high performance switch can control a load of up to 0.8 A.

This device switch includes an overvoltage crowbar 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.

Applications

? Alternating current on/off static switching in appliances and industrial control

systems

? Driving low power high inductive or resistive loads like:

– relay, valve, solenoid, dispenser

– pump, fan, low power motor, door lock, air flow dumper

– lamp
