Principles for replacing rectifier diodes

Principles for replacing rectifier diodes

If the rectifier diode is replaced in a circuit, the following principles must be known:

1、 You can choose to use diodes with similar model parameters and the original diode model parameters for replacement.

2、 A diode with a large rectifier current can replace a diode with a small rectifier current, but on the contrary, it cannot be replaced.

3、 A diode with a high reverse working voltage can replace a diode with a low reverse voltage, but on the contrary, it cannot be replaced.

4、 A diode with a high operating frequency can replace a diode with a low operating frequency, but on the contrary, it cannot be replaced.

The application of rectifier diodes in diode circuits is the most common. The so-called rectifier diode is a diode specifically used for converting alternating current into unidirectional pulsating direct current in power circuits. The circuit composed of rectifier diodes is called a diode rectifier circuit.
