Overview

The 1N5818-E3/54 is a through-hole Schottky barrier rectifier designed for low-voltage, high-frequency rectification. It features a 1A average rectified current rating and a 30V maximum DC reverse voltage in a standard DO-41 axial package. The device utilizes a guardring for overvoltage protection and offers extremely fast switching speeds with minimal conduction losses.

Why Choose This Part

This diode offers a low forward voltage drop and high-frequency operation capability up to 10000 V/us slew rate. Its DO-41 through-hole package is ideal for breadboarding, prototyping, and robust mechanical mounting in industrial environments.

Applications

DC/DC Converters
Used as a high-frequency rectifier in small power supply circuits to improve efficiency.
Freewheeling Diode
Provides a discharge path for inductive loads in motor drivers and relay circuits.
Polarity Protection
Protects sensitive downstream electronics from accidental battery reversal with low forward voltage drop.
Low Voltage Inverters
Enables efficient switching in high-frequency inverter applications.

Getting Started

When integrating this diode, ensure the cathode (marked with a band) is correctly oriented toward the more positive potential in rectification circuits. For high-current applications, keep lead lengths short to minimize parasitic inductance and ensure the junction temperature stays within the -65C to 125C range.

Also Consider

1N5817-E3/54 VSHVishay - Lower 20V reverse voltage but offers a lower forward voltage drop for increased efficiency in very low voltage circuits.
1N5819-E3/54 VSHVishay - Provides a higher 40V reverse voltage rating for applications requiring more headroom.
