What are the differences between fast recovery diodes and regular diodes?
Fast recovery diode: The forward voltage drop is higher than that of ordinary diodes (0.5-2V), and the reverse voltage withstand is mostly below 1200V.
Ordinary diode: It has a forward voltage reduction (0.4-1.0V), a short reverse recovery time (2-10ns nanoseconds), and a large reverse leakage current, with low withstand voltage, generally below 150V, and is mostly used in low voltage applications.
Fast recovery diode:
Fast Recovery Diode (FRD) is a semiconductor diode with good switching characteristics and short reverse recovery time. It is mainly used in electronic circuits such as switching power supplies, PWM pulse width modulators, and frequency converters as a high-frequency rectifier
Use current diodes, freewheeling diodes, or damping diodes. The internal structure of a fast recovery diode is different from that of a regular PN junction diode. It belongs to the PIN junction type diode, which adds a base region I between P-type silicon material and N-type silicon material to form a PIN silicon wafer. Due to the thin base region and small reverse recovery charge, fast recovery diodes have a shorter reverse recovery time, lower forward voltage drop, and higher reverse breakdown voltage (withstand voltage value).
A diode is a device in electronic components that has two electrodes and allows current to flow in only one direction. Many uses it for rectification purposes. Varicap diodes are used as electronic adjustable capacitors. The current directionality possessed by most diodes is commonly referred to as the "rectifying" function. The most common function of a diode is to allow current to pass only in a single direction (known as forward bias), and to block it in reverse (known as reverse bias).
