A rectifier diode is a semiconductor device that converts alternating current (AC) energy into direct current (DC) energy. It typically contains a PN junction with two terminals, one positive and one negative. The critical characteristic of diodes is their unidirectional electrical conductivity, where current can only flow from the positive pole to the negative pole within a circuit.

To inspect a rectifier diode, first remove it from the rectifier. Using a multimeter set to the 100XR or 1000XR ohm range, measure the resistance of the two lead wires, swapping the head and tail of the diode once during the measurement. If the resistance values differ significantly, for example, ranging from several hundred kΩ to infinity for high resistance values, and only a few hundred Ω or less for low resistance values, then the diode is in good condition (excluding diodes that have experienced soft breakdown). If the resistance values measured are almost equal and very small, this indicates that the diode has been damaged by breakdown and is no longer usable. If the resistance values measured are both infinite, the diode has been internally disconnected and cannot be used.

The product in question is the IN5406 3A 600V Silicon Rectifier Direct Insert Diode. Its key features include a low forward voltage drop, low reverse leakage current, and high rated surge current. The diode consists of a PN junction with positive and negative terminals and is housed in a molded plastic, flame-retardant epoxy resin package. The product is packaged with 120 pieces per container.
