5SHX0660F0002额定通态平均电流在一定条件下，阳极---阴极间可以连续通过的50赫兹正弦半波电流的平均值。5SHX0660F0002正向阻断峰值电压在控制极开路未加触发信号，阳极正向电压还未超过导能电压时，可以重复加在可控硅两端的正向峰值电压。

可控硅承受的正向电压峰值，不能超过手册给出的这个参数值。5SHX0660F0002反向阴断峰值电压当可控硅加反向电压，处于反向关断状态时，5SHX0660F0002可以重复加在可控硅两端的反向峰值电压。使用时，不能超过手册给出的这个参数值。

 控制极触发电流在规定的环境温度下，阳极---阴极间加一定电压，使可控硅从关断状态转为导通状态所需要的小控制极电流和电压。维持电流在规定温度下，控制极断路，维持可控硅导通所必需的小阳极正向电流。

5SHX0660F0002采用可控硅技术对照明系统进行控制具有：电压调节速度快，精度高，可分时段实时调整，有稳压作用，采用电子元件，5SHX0660F0002相对来说体积小、重量轻 低。但该调压方式存在一致命缺陷，由于斩波，使电压无法实现正弦波输出，还会出现大量谐波，形成对电网系统谐波污染，危害 ，不能用在有电容补偿电路中。

5SHX0660F0002 Average current in rated on-state The average 50 Hz sinusoidal half-wave current that can be passed continuously between anode and cathode under certain conditions. 5SHX0660F0002 Forward blocking peak voltage When the control pole is open without a trigger signal and the anode forward voltage does not exceed the conductance voltage, the forward peak voltage at both ends of the thyristor can be repeated.

The peak forward voltage of the thyristor cannot exceed the parameter value given in the manual. 5SHX0660F0002 Reverse negative peak voltage When the thyristor is in the reverse off state, 5SHX0660F0002 can repeat the reverse peak voltage at both ends of the thyristor. Do not exceed this parameter value given in the manual.

At the specified ambient temperature, a certain voltage is added between the anode and cathode to make the thyristor change from the off state to the on-state required small control electrode current and voltage. Maintain current At the specified temperature, the control pole is broken, and the small anode forward current necessary to maintain the thyristor conduction is maintained.
