performance tests for fast recovery diodes

 performance tests for fast recovery diodes

When selecting and purchasing fast recovery diodes, their performance needs to be tested. The specific methods are as follows

100% with a multimeter × R or 1000 × Measure the two outgoing lines of the fast recovery diodes rectifier diode in the R ohm range (with the head and tail swapped once each). If the resistance values measured twice differ significantly, such as those with high resistance values reaching several hundred thousand Ω and those with low resistance values being only a few hundred Ω or even smaller, it indicates that the diode is good (except for those with soft breakdown). If the resistance values measured twice are almost equal and the resistance values are very small, it indicates that the diode has been broken down and cannot be used.
