What are Power Diodes?Power Diode A power diode is defined as a diode used in power electronics circuits, capable of handling higher currents than regular diodes. It has two terminals and conducts current in one direction, with a construction designed for higher power applications.To understand power diodes better, let’s revisit how a standard diode works. A diode is defined as the simplest semiconductor device, with two layers, two terminals, and one junction.Ordinary signal diodes have a junct

What is a Schottky Diode?Schottky Diode definitionThe reverse recovery time is extremely short (can be as small as a few nanoseconds), the positive pilot voltage drop is only about 0.4V, and the rectification current can reach thousands of amps, which can be used as a switching diode and a low-voltage high-current rectifier diode.Schottky Diode structureIt is formed by connecting doped semiconductor regions (usually N-type) with metals such as gold, platinum, titanium, etc. The formation is not

What is a Fast Recovery Power Diode?Fast recovery power diode definitionSemiconductor diodes with good switching characteristics and short reverse recovery time are mainly used in switching power supplies, PWM pulse width modulators, frequency converters and other electronic circuits as high-frequency rectifier diodes, continuous current diodes or damping diodes.Fast recovery power diode performance characteristics The reverse recovery time is short The reverse recovery charge is smallDetection

What is a Power Diode?Power DiodedefinitionBased on semiconductor PN, its on-off and off-off are completely determined by the voltage and current it undergoes in the main circuit, which can realize the function of positive on-off and reverse cutoff, and the power diode is an uncontrollable device.How Power Diodes workWhen the PN junction is applied with a forward voltage, that is, P→+, N→-, the external electric field is opposite to the internal electric field, and the diffusion motion is greate
