BTA12屬于分立半導(dǎo)體產(chǎn)品的晶閘管-TRIAC。由意法半導(dǎo)體集團制造生產(chǎn)的BTA12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。

描述 Description

Available either in through-hole or surface-moun packages, the BTA12, BTB12 and T12xx triac series is suitable for general purpose mains power AC switching.

特性 Features

■ Medium current triac

■ Low thermal resistance with clip bonding

■ Low thermal resistance insulation ceramic for insulated BTA

■ High commutation (4Q) or very high commutation (3Q) capability

■ BTA series UL1557 certified (File ref: 81734)

■ Packages are RoHS ( 2002/95/EC) compliant

Applications

ON/OFF or phase angle function in applications such as static relays, light dimmers and appliance motors speed controllers.

The snubberless versions (BTA/BTB...W and T12 series) are especially recommended for use on inductive loads, because of their high commutation performances. The BTA series provides an insulated tab (rated at 2500 V RMS).
