Appearance recognition: Crystal diodes typically have a slender positive (anode) lead and a short negative (cathode) lead.
Reverse voltage measurement: Using a multimeter or digital voltmeter
Brand and Quality: Choose well-known brand diodes and pay attention to quality assurance.
A crystal diode, also known as a semiconductor diode or simply a diode, is essentially a PN junction.
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.
