描述 Description

AC Thyristor power switch in a SOT223 surface-mountable plastic package with self-protective capabilities against low and high energy transients.

特性 Features

? Common terminal on mounting base allows multiple ACTs on shared cooling pad
? Exclusive negative gate triggering
? Full cycle AC conduction
? High voltage capability
? Remote gate separates the gate driver from the effects of the load current
? Safe clamping of low energy over-voltage transients
? Self-protective turn-on during high energy voltage transients
? Surface-mountable package
? Very high noise immunity

應(yīng)用 Application

? Fan motor circuits
? Pump motor circuits
? Lower-power highly inductive, resistive and safety loads
? Contactors, circuit breakers, valves, dispensers and door locks

簡介

ACT108W-800E屬于分立半導(dǎo)體產(chǎn)品的晶閘管-TRIAC。由制造生產(chǎn)的ACT108W-800E晶閘管 - TRIAC晶閘管可沿一個方向或在半個 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，即會沿任一方向傳導(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)電壓進行選擇。
