The 1N5819 is a popular Schottky barrier rectifier diode featuring low forward voltage drop and fast switching. Its 40V reverse voltage rating and 1A current capacity make it ideal for power supply circuits, flyback protection, and solar panel applications.
Schottky diodes have a lower forward voltage drop (typically 0.3-0.6V) compared to standard silicon diodes, resulting in less power loss and heat generation in your circuits.
Key Features
- Low Forward Voltage – Typically 0.6V at 1A, reducing power losses
- Fast Switching – Ideal for high-frequency applications
- 1A Current Rating – Suitable for most low to medium power circuits
- 40V Reverse Voltage – Adequate headroom for common DC applications
- Through-Hole Package – Easy to solder and prototype with

Jargon buster
Plain-language definitions for the technical terms used above.
- Forward voltage drop
- Forward voltage drop is the small amount of voltage lost across a diode or diode-like circuit when current flows through it. A lower drop is important because it wastes less power and helps keep the rest of the project supplied with enough voltage.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- reverse polarity protection
- A circuit feature that helps protect the board if power is connected the wrong way around. It matters because it can reduce the chance of damaging the breakout during wiring mistakes, especially in classroom or prototyping use.
