AVS12CB分立半导体产品的晶闸管-TRIAC规格书PDF中文资料

AVS12CB属于分立半导体产品的晶闸管-TRIAC。由意法半导体集团制造生产的AVS12CB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。

DESCRIPTION

The AVS12 kit is an automatic mains selector (110/220V AC) to be used in SMPS < 500 W. It is composed of 2 devices :

■ The Controller is optimized for low consumption and high security triggering of the triac. When connected to VSS, the mode input activates an additional option. If the main power drops from 220V to 110V, the triac control remains locked to the 220V mode and avoids any high voltage spike when the voltage is restored to 220V. When connected to VDD, the mode input desactivates this option.

■ The TRIAC is specially designed for this application. An optimization between sensitivity and dynamic parameters of the triac gate highly reduces the losses of supply resistor and allows excellent immunity against disturbances.
