How to choose a diode in bridge rectification?

How should the diode in the bridge rectifier circuit be selected? In addition to understanding the characteristics of the bridge rectifier circuit, we must also understand the basic situation of the bridge rectifier circuit.

Diode in bridge rectification: germanium diode selection when low on-voltage is required; Silicon diode selection when high on-voltage is required; Requires reverse current hourly silicon diode selection.

Bridge rectifiers utilize four diodes, two coupled. The positive half of the input sine wave is that the two tubes are turned on to get a positive output; When the negative half of the sine wave is input, the other two tubes are turned on, and since the two tubes are reversed, the output still gets the positive half of the sine wave. Bridge rectifiers utilize input sine waves twice as efficiently as half-wave rectification. bridge rectification is the first step in the conversion of alternating current to direct current.

Bridge rectifier is made of multiple rectifier diodes for bridge connection, external insulation plastic packaging, high-power bridge rectifier in the insulation layer added metal shell encapsulation to enhance heat dissipation. There are many varieties of bridge rectifiers, excellent performance, high rectification efficiency, good stability, the maximum rectifier current from 0.5A to 50A, and the highest reverse peak voltage from 50V to 1000V.
