BTB12中文资料12A标准和Snubberless™三端双向可控硅数据手册ST规格书

描述 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.

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 (2011/65/EU) compliant

简介

BTB12属于分立半导体产品的晶闸管-TRIAC。由制造生产的BTB12晶闸管 - TRIAC晶闸管可沿一个方向或在半个 AC 周期内传导 AC（交流电）。当 TRIAC（三极管 AC）的门极被触发时，即会沿任一方向传导电流。其他名称包括双向三极晶闸管或双侧三极晶闸管。TRIAC 分为无缓冲器、Alternistor、内部触发、逻辑门和标准型，安装方式包括底座、表面或通孔安装。这些器件可根据断态电压、通态电流、保持电流和门极触发电压进行选择。
