Description

Available either in through-hole or surface mount packages, the BTA12, BTB12 and

T12xx Triac series are suitable for general purpose mains power AC switching. They

can be used as ON/OFF function in applications such as static relays, heating

regulation or induction motor starting circuit. They are also recommended for phase

control operations in light dimmers and appliance motors speed controllers.

The Snubberless? versions (W suffix and T12xx) are especially recommended for

use on inductive loads, because of their high commutation performance. By using an

internal ceramic pad, the Snubberless? series provide an insulated tab (rated at

2500 VRMS) complying with UL standards (file reference: E81734).

Logic Level BTA12-600TW and BTA12-600SW offer low holding current, ideal to

design light dimmers for LED lamps.

BTB12-800BRG屬于分立半導體產品 > 晶閘管 - TRIAC。意法半導體（ST）集團制造生產的BTB12-800BRG晶閘管 - TRIAC晶閘管可沿一個方向或在半個 AC 周期內傳導 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三極晶閘管。TRIAC 分為無緩沖器、Alternistor、內部觸發(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。
