串入一个二极管或两个反向并联的二极管可以作为一种有用的替代方法，起上述串联电阻的作用。
A series diode, or two diodes in parallel back-to-back, can serve as a useful alternative to a series resistor for this purpose.
这类应用可能包括电容器的漏电流、二极管反向漏电、电缆或薄膜的绝缘电阻等。
Some of these applications may include leakage current of capacitors, reverse diode leakage, or insulation resistance of cables or films.
