与双向可控硅（TRIAC）元件连接的缓冲电路的常数值应如何选择？
可变电容二极管缩写为VCD。其也被称为变容二极管。
可变电容二极管具有可变电容，该可变电容为阳极与阴极之间的电压函数。
通用型二极管用于整流和信号检测，可变电容二极管用于自动调谐器和发射器中的射频（RF）阻抗匹配。
插入缓冲电路以抑制突然升高的电压（dV／dt），从而防止故障。东芝建议对于100V交流系统采用RS＝47Ω和CS＝0.033μF，对于200V交流系统，则采用RS＝100Ω和CS＝0.1μF。
参阅东芝应用说明《Triac couplers-basic properties and application design》第9.6节。
