## Description

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 Ideal For Power supply rectification Reverse polarity protection Flyback/freewheeling diode for motors and relays Solar panel blocking diodes Arduino and microcontroller projects Specifications Part Number: 1N5819 Diode Type: Schottky Barrier Rectifier Maximum Reverse Voltage: 40V Maximum Forward Current: 1A Forward Voltage Drop: 0.6V typical @ 1A Package: DO-41 (through-hole) Material: Silicon Warranty: 3 months Package Contents 1× 1N5819 Schottky Diode
