Diode Classification Methods

By Frequency Classification: The most fundamental classification method. Diodes are categorized based on their characteristics into rectifier diodes, switching diodes, Schottky barrier diodes, Zener diodes, and high-frequency diodes for high-frequency applications. Additionally, Zener diodes are commonly used as protective components. However, with the increasing precision of peripheral circuits and the miniaturization of applications, there is a growing demand for higher-performance protective components — such as TVS (Transient Voltage Suppressor).
By Structure Classification: Mainly divided into the currently mainstream planar type and the high-voltage-resistant mesa type.
By Forward Current Classification: Based on the magnitude of forward current, diodes with I_F less than 1A are referred to as small-signal diodes, while those with I_F of 1A or above are termed medium-power/high-power diodes.
By Package Classification: Packaging, or the physical installation form. Diodes come in various shapes, broadly categorized as through-hole (plugin) type and surface-mount (SMD) type.
