自动电压开关由面向120/240 V双电压应用的三端双向可控硅开关专用驱动器组成。 该控制器具有50/60 Hz兼容性、三端双向可控硅开关的触发脉冲串、寄生滤波器和低功耗等特点。 三端双向可控硅开关器件的最大额定电压为600 V、最大电流高达12 A。
驱动器采用DIP 8封装，而三端双向可控硅开关则采用TO-220和TO-220I 封装。
ST’s 8H Triacs have been designed for Industrial, Building, Residential, Appliances. Based on the new ST’s technology, the 8H Triacs are able to work at 800V & 150°C without compromise. It makes 8H Triacs the right choice to run in very hot confined electronic environment and improve the reliability of your system. Thanks to 8H Triacs robust dynamic turn-off commutation and high noise immunity at high temperature you can reduce your system size while increasing functional safety.
