Description

Available in the Faston terminal RD91 package, the BTA25 is suitable for general

purpose AC switching and provides an insulated tab (rated at 2500 VRMS).

Representative samples of these components have been evaluated by UL and meet

applicable UL requirements for UL 1557 standard (file ref. 81734).

BTA25-800BW属于分立半导体产品 > 晶闸管 - TRIAC。意法半导体（ST）集团制造生产的BTA25-800BW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。
