Summary
This application note serves as a guide for selecting rectifier diodes used in commercial power supplies and switching power supplies. It outlines the four primary types of rectifier diodes: general rectifier diodes (REC), fast recovery diodes (FRD), silicon Schottky barrier diodes (Si-SBD), and silicon carbide Schottky barrier diodes (SiC-SBD). Each type is described in terms of its electrical characteristics, including forward voltage (VF), reverse current (IR), reverse recovery time (trr), and breakdown voltage (VR). The document provides a comparison of these features to assist in identifying suitable applications for each diode type. Additionally, it discusses the importance of selecting the right diode based on specific circuit requirements, such as efficiency and speed. The note emphasizes the trade-offs between characteristics like VF and trr, which are critical for optimizing performance in various applications.
