Description

Available either in through-hole or surface-mount packages, the BTA24, BTB24, BTA25, BTA26 and T25triac series is suitable for general purpose AC switching. They can be used as an ON/OFF function in applications such as static relays, heating regulation, induction motor starting circuits... or for phase control operation in light dimmers, motor speed controllers, ...

The snubberless versions (BTA/BTB...W and T25 series) are specially recommended for use on inductive loads, thanks to their high commutation performances. By using an internal ceramic pad, the BTA series provides voltage insulated tab (rated at 2500VRMS) complying with UL standards (File ref.: E81734).

BTA25-800B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BTA25-800B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。
