Rectifier diodes are generally planar silicon diodes, which are used in various power rectifier circuits.
When choosing a rectifier diode, the parameters such as its maximum rectifier current, maximum reverse working current, cut-off frequency, and reverse recovery time should be considered.
The rectifier diodes used in ordinary series regulated power supply circuits do not have high requirements on the reverse recovery time of the cut-off frequency, as long as the rectifier diodes with the maximum rectification current and the maximum reverse working current meet the requirements according to the requirements of the circuit. For example, 1N series, 2CZ series, RLR series, etc.
The rectifier diodes used in the rectifier circuit of the switching regulated power supply and the pulse rectifier circuit should be rectifier diodes with higher operating frequency and shorter reverse recovery time (such as RU series, EU series, V series, 1SR series, etc.) or Fast recovery diode.
Selection of rectifier diodes
Rectifier diodes are generally planar silicon diodes, which are used in CPPCC power rectifier circuits.
When choosing a rectifier diode, parameters such as its maximum rectifier current, maximum reverse working current, cut-off frequency and reverse recovery time should be considered.
The rectifier diodes used in ordinary series regulated power supply circuits do not have high requirements on the reverse recovery time of the cut-off frequency, as long as the rectifier diodes with the maximum rectification current and the maximum reverse working current meet the requirements according to the requirements of the circuit.
The rectifier diode used in the rectifier circuit of the switching regulated power supply and the pulse rectifier circuit should choose a rectifier diode with a high operating frequency and a short reverse recovery time or a fast recovery diode.
Replacing Rectifier Diodes
After the rectifier diode is damaged, it can be replaced with the same type of rectifier diode or other types of rectifier diodes with the same parameters.
Generally, rectifier diodes with high withstand voltage (reverse voltage) can replace rectifier diodes with low withstand voltage, while rectifier diodes with low withstand voltage cannot replace rectifier diodes with high withstand voltage. A diode with a high rectified current value can replace a diode with a low rectified current value, while a diode with a low rectified current value cannot replace a diode with a high rectified current value.
