Schottky Diode 1N5822

The Schottky Diode 1N5822 is a 3 A, 40 V Schottky barrier rectifier in an axial DO-201AD package. Compared with a standard silicon rectifier such as the 1N4007, it has a much lower forward voltage drop and switches very fast, so it wastes less power as heat. This makes it a common choice for switching regulators, solar charging circuits and reverse polarity protection on DC inputs.

Schottky Diode 1N5822 Specifications

• Type: Schottky barrier rectifier diode
• Repetitive peak reverse voltage: 40 V
• Average forward current: 3 A
• Forward voltage: max 0.525 V at 3 A
• Peak surge current: 80 A (8.3 ms half sine wave)
• Package: DO-201AD, axial leads, through-hole
• Polarity: the band on the body marks the cathode

Schottky Diode 1N5822 Applications

• Catch (freewheeling) diode in buck converters such as LM2596 circuits
• Reverse polarity protection on DC power inputs
• Blocking diodes in small solar panel and battery charging circuits
• OR-ing two power sources
• Low-voltage, high-frequency rectification

What's in the Box

• 1 × 1N5822 Schottky diode

Tip: The band on the body marks the cathode (−). Schottky diodes leak more current in reverse than standard diodes, especially when hot, so keep the reverse voltage well below 40 V and leave some lead length to help the diode cool at high currents.
