整流二极管最高反向电压一般是指可以承受的最大反向电压，也叫反向击穿电压。当整流二极管处于反向电压下，如果反向电压过大，将会导致电子从整流二极管中流过，从而烧毁电路。因此，在实际应用中，需要选择合适的整流二极管来承受所需要的最大反向电压。

那么如何测量整流二极管最高反向电压及最高整流电流呢？要测量最高反向电压，需要使用反向电压测量仪。首先将整流二极管反向连接至反向电压测量仪，电源打开，保持反向电压稳定不变，逐渐增加反向电压，直到整流二极管击穿。读取此时的反向电压值，该值即为整流二极管的最高反向电压。

需要注意的是，反向电压测量时需要注意电流容量，如果电流过大可能会烧毁测量仪器。要测量最高整流电流，可以使用实验电源和串联电流表进行测量。

首先串联电流表到实验电源的负极上，将正极连接到整流二极管的正极，反向连接整流二极管的正极与实验电源的负极，调整实验电源的电流输出，逐渐提高电流直到整流二极管损坏，读取此时的电流值，该值即为整流二极管的最高整流电流。需要注意的是，在测量最高整流电流时需要防止实验电源电流和电压过大，应选择合适的电流表和电源进行测量。

整流二极管最高反向电压和最高整流电流是选择和使用整流二极管时需要重点考虑的参数。在实际应用中，需要根据具体电路要求选择合适的整流二极管，并严格按照规定的电流和电压范围使用，以确保电路的性能和可靠性。
