ACST4分立半導體產(chǎn)品的晶閘管-TRIAC規(guī)格書PDF中文資料

ACST4屬于分立半導體產(chǎn)品的晶閘管-TRIAC。由意法半導體集團制造生產(chǎn)的ACST4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。

Description
