Types of Rectifier Diodes

Standard Diodes (Silicon PN Junction) Standard diodes are the most basic type of rectifier diode, made from silicon with a PN junction. They’re commonly used in AC-to-DC converters, power rectification, and general circuit protection. These diodes typically have a forward voltage drop around 0.7V and are best suited for low-frequency switching. Their reverse recovery time (how quickly they stop conducting when switched off) is relatively slow, which limits their use in high-speed applications. They also have low reverse leakage current, which makes them reliable for steady-state operations.

Schottky Barrier Diodes (SBD)
Schottky diodes (SBDs) use a metal-semiconductor junction instead of a traditional PN junction, resulting in faster switching speeds and lower forward voltage drops—often between 0.2V and 0.4V. This makes them ideal for DC-DC converters, high-efficiency power supplies, and circuits where minimizing power loss is critical. However, one drawback of SBDs is their higher reverse leakage current, especially at elevated temperatures, which can be a concern in precision or battery-operated devices.

Super Barrier Rectifiers (SBR)
Super Barrier Rectifiers (SBRs) combine the best traits of standard diodes and Schottky diodes. They offer low forward voltage drop like SBDs, but with significantly lower reverse leakage current and improved reverse voltage handling. SBRs are well-suited for switching power converters, adapters, and automotive electronics, where energy efficiency and thermal stability are important. They’re often a better choice than Schottky diodes when the application involves higher ambient temperatures or larger voltage transients.

Avalanche Diodes
Avalanche diodes are designed to operate reliably in reverse breakdown mode, where they safely conduct current once a specific reverse voltage threshold is exceeded. Unlike standard diodes that can be damaged by breakdown, avalanche diodes are built to handle this condition repeatedly and predictably.

Silicon Carbide (SiC) Diodes
SiC diodes are built from silicon carbide, a wide-bandgap material that allows them to handle very high voltages (600V and up) and extreme temperatures (>150°C). They are ideal for industrial converters, electric vehicle chargers, solar inverters, and motor drives, especially in circuits requiring fast switching and zero reverse recovery time. Although more expensive than silicon-based diodes, their durability and efficiency at high voltages and frequencies often make them the best long-term choice in demanding applications.
