Product Description
Product Description:
A rectifier diode is a semiconductor device that converts alternating current energy into direct current energy.
Usually it contains a PN junction with two terminals, positive and negative
The important characteristic of diodes is their unidirectional electrical conductivity.
In a circuit, current can only flow in from the positive pole of the diode and out from the negative pole.
Product self inspection:
First, remove all the rectifier diodes from the rectifier,
Using the 100XR or 1000XR ohm range of a multimeter,
Measure the two lead wires of the rectifier diode (swap the head and tail once each).
If the resistance values measured twice differ significantly,
For example, for high resistance values ranging from several hundred K Ω to infinity,
And those with low resistance values are only a few hundred Ω or even smaller,
Indicates that the diode is good (excluding diodes that have experienced soft breakdown)
If the resistance values measured twice are almost equal and the resistance values are very small,
This indicates that the diode has been damaged by breakdown and cannot be used.
If the resistance values measured twice are both infinite,
This diode has been internally disconnected and cannot be used.
