In a world where time and efficiency matter - discover fast Schottky diodes

2026-03-03

Maximum Efficiency in Every Microsecond

The 1N5822, SS18 and SS36 diodes are members of the Schottky diode family - semiconductor components that, thanks to their design, offer a low forward voltage drop and very fast switching performance. Unlike traditional silicon diodes, where conduction occurs through a p-n junction, Schottky diodes use a metal-semiconductor junction. This structural difference eliminates the classic reverse recovery time, resulting in significantly more dynamic performance in switching applications.

These models combine fast operation, low power losses, and high reliability. As a result, they are essential components in modern energy-efficient electronic systems, where every microsecond of switching time and every watt of loss directly affect overall system efficiency.

Key Features:

  • Low forward voltage drop (VF) - Typically in the range of 0.5-0.85V, depending on the model and current, resulting in lower energy losses and higher efficiency compared to conventional silicon diodes.
  • Very fast switching - No classical reverse recovery effect (virtually instantaneous switching), making these diodes ideal for high-frequency switching converters.
  • High energy efficiency - Lower power dissipation (P = I × VF) means reduced heat generation, leading to improved reliability and longer system lifetime.

Current Ratings:

  • 1N5822 - 3A
  • SS18 - 1A
  • SS36 - 3A

Reverse Voltage (VRRM):

  • 1N5822 - 40V
  • SS18 - 80V
  • SS36 - 60V

Applications:

  • DC/DC converters and switching power supplies (SMPS), where low losses and fast switching are critical
  • Low-voltage, high-current rectifier circuits
  • Reverse polarity protection
  • OR-ing circuits (combining multiple power sources)
  • Filtering and pulse circuits
  • Low-voltage photovoltaic systems
  • Battery-powered devices and 12V/24V systems

Summary

The 1N5822, SS18 and SS36 are fast Schottky diodes rated up to 3A with reverse voltages from 40 to 80V, designed for switching and power supply applications. Their low forward voltage drop, absence of reverse recovery effect, and high surge current capability make them an optimal choice for modern high-efficiency power electronics.
