Discrimination between positive and negative poles: Some varactor diodes have a black mark on one end, which is the negative pole, and the other end is the positive pole. Some varactor diodes have yellow and red rings painted on both ends of their casing, with one end of the red ring being the positive electrode and the other end of the yellow ring being the negative electrode

The main function of rectifier diodes in electronic circuits is to convert alternating current into direct current. AC power is a current with alternating positive and negative voltages, while DC power is a current with a constant voltage. Rectifiers can rectify alternating current through their special electronic flow mechanism.

The rectifier diode in a switching power supply must have the characteristics of forward voltage reduction and fast recovery, as well as sufficient output power. The following three types of rectifier diodes can be used: fast recovery rectifier diode; Ultra fast recovery rectifier diode; Schottky rectifier diode. Fast recovery and ultra fast recovery rectifier diodes have moderate and high forward voltage drops, ranging from 0.8 to 1.2V. These two rectifier diodes also have high cutoff voltage p
