DIOTEC super-fast diodes are specialised semiconductor components designed for applications requiring very short recovery times (15–200 ns). This is a key parameter in the design of modern converters, switching power supplies, flyback circuits and high-frequency systems, where standard or fast diodes do not meet the dynamic requirements.

The technical parameters range from reverse voltages up to 1000 V, forward currents up to 30 A and forward voltages in the range of 0.89–1.75 V. These characteristics make DIOTEC superfast diodes suitable for both low-power circuits and heavy-duty industrial applications. Short switching times reduce power losses and electromagnetic interference (EMI), which translates into greater system efficiency and stability.

The products are available in versions for surface mounting (SMD) and through-hole mounting (THT). The available housings include, among others SOD-123FL, MiniMelf, SMA, SMB, SMC, DO-41, DO-201, TO-220, ITO-220, D8x7.5 and TO-263AB/D2PAK. Such a wide selection allows for easy integration of components in designs with different mounting and space requirements.

Applications for DIOTEC ultra-fast diodes include:

• switching power supplies and DC/DC converters,
• high-frequency rectifier circuits,
• inverters, UPS systems, chargers,
• Class D audio systems,
• automation and industrial electronics devices.

High quality, durability and compliance with standards make these components a reliable solution for both commercial applications and professional industrial systems.
