Maximum reverse operating voltage URM. The maximum reverse voltage specified to ensure the normal operation of a diode without breakdown is often referred to as the rated operating voltage.
When the forward voltage (P is positive and N is negative) at both ends of the diode is very small (germanium tube is less than 0.1 volts
When the reverse voltage increases to a certain value,
At rated power, the current value allowed to pass through the diode.
