Can fast recovery diodes and rectifier diodes be used interchangeably?

The internal structure of a fast recovery diode is different from that of a regular diode, as it adds a base region I between P-type and N-type silicon materials to form a P-I-N silicon wafer. Due to the thin base region, the reverse recovery charge is very small, which not only greatly reduces the TRR value, but also reduces the transient forward voltage drop, allowing the tube to withstand high reverse operating voltages. A rectifier diode is a semiconductor device that converts alternating current energy into direct current energy. It usually contains a PN junction with two terminals, positive and negative. Rectifiers are generally planar silicon diodes used in various power rectifier circuits.
What is the difference between fast recovery diodes and rectifier diodes? Analyze from the following three aspects. Fast recovery diode: Due to its thin base region and small reverse recovery charge, the fast recovery diode not only greatly reduces the TRR value but also lowers the transient forward voltage drop, allowing the tube to withstand high reverse operating voltages. Rectifiers: Rectifiers utilize the unidirectional conductivity of PN junctions to convert alternating current into pulsating direct current. The leakage current of rectifier diodes is relatively large, and most diodes are packaged with surface contact materials. Different structure, fast recovery diode: The internal structure of a fast recovery diode is different from that of a regular diode. It adds a base region I between P-type and N-type silicon materials to form a P-I-N silicon wafer. Rectifying diode: Usually it contains a PN junction with two terminals, positive and negative. The most important characteristic of a diode is its unidirectional conductivity. In a circuit, current can only flow in from the positive pole of a diode and out from the negative pole. Therefore, to summarize, several principles can be considered for the replacement of rectifier diodes:

① The rectifier diode with a higher maximum average rectified current can replace the diode with a lower rectified current, but the reverse is not feasible;

② A rectifier diode with a high reverse operating voltage can replace a rectifier diode with a low reverse voltage, but not the other way around;

③ A rectifier diode with a high operating frequency can replace a rectifier diode with a low operating frequency, but not vice versa.

In addition, the price of fast recovery diodes is much higher compared to rectifier diodes, and the higher the withstand voltage, the more expensive it is. Therefore, fast recovery diodes are generally not used as substitutes. Of course, if you only have a fast recovery diode at hand and do not have a regular rectifier tube, as long as the withstand voltage is sufficient, it can also be used as a substitute.
