Specifications

Key Features

• Ultra-Low Forward Voltage Drop: Only 0.6V typical at rated current - significantly lower than standard silicon diodes (1N4007 drops ~1.1V), reducing power loss and heat generation in your circuits.
• Fast Switching Performance: Schottky barrier construction enables nanosecond-class switching with negligible reverse recovery time, ideal for high-frequency applications up to several MHz.
• 1A Current Handling: Rated for 1A continuous forward current with 25A surge capability, providing reliable performance in demanding power circuits.
• 40V Reverse Voltage Rating: Suitable for low-to-medium voltage applications including 5V, 12V, and 24V power systems.
• Wide Temperature Range: Operates reliably from -65 degreesC to +125 degreesC, suitable for both indoor projects and harsh environment deployments.
• Standard DO-41 Package: Breadboard and PCB-friendly axial lead through-hole package with clear cathode band marking for easy identification and soldering.
• Pack of 5: Convenient quantity for projects requiring multiple diodes - enough for prototyping, testing, and building complete circuits.

Why Choose the 1N5819 Schottky Diode?

• Lower Power Loss: The Schottky barrier junction delivers roughly half the voltage drop of conventional PN-junction diodes, meaning less wasted energy and cooler operation in your power circuits.
• Superior to 1N4001-1N4007 for Low-Voltage Work: When working with 3.3V or 5V logic systems, every millivolt counts - the 1N5819's low VF preserves precious voltage headroom.
• Essential for Solar and Battery Circuits: The low drop maximizes energy harvesting efficiency in solar panel charge controllers and minimizes battery drain in reverse polarity protection.
• Industry-Standard Reliability: The 1N5819 is one of the most widely used Schottky diodes in the world, backed by decades of proven performance across millions of designs.
• 100% Authentic Components: Sourced directly from authorized distributors - no counterfeits, no remarked parts, no compromises.
• 1-5 days shipping: Ships from our Bengaluru warehouse to most locations across India. Same-day delivery available in Bengaluru.
• Expert Technical Support: Our engineering team is available 24/7 to help with circuit design questions, component selection, and troubleshooting.

How the 1N5819 Works

Unlike conventional silicon PN-junction diodes, the 1N5819 uses a metal-semiconductor (Schottky) junction formed between a metal layer and an N-type semiconductor. This construction eliminates the minority carrier storage effects found in standard diodes, resulting in two major advantages: a significantly lower forward voltage drop (0.6V vs. 1.0-1.1V for standard diodes) and virtually zero reverse recovery time. When forward biased, current flows with minimal voltage penalty. When reverse biased, the diode blocks current up to 40V. The absence of reverse recovery delay makes it ideal for high-frequency switching applications where standard diodes would introduce unacceptable losses and noise.
