1N5817 A0G

Overview

The Taiwan Semiconductor Corporation 1N5817 A0G is a Schottky barrier rectifier featuring a single silicon element in a DO-41 axial through-hole package. It supports an average forward current of 1 A and a maximum repetitive peak reverse voltage of 20 V. The device exhibits a maximum forward voltage drop of 750 mV at rated current and withstands a peak forward surge current of 25 A. Operating junction temperatures range from -65 °C to +125 °C, with a specified maximum reverse leakage current of 500 µA.

Feature Summary

• Schottky barrier construction for low power loss and high efficiency
• Guard ring die design for transient protection capability
• Extremely fast switching characteristics with negligible recovery charge

Applications

• Low voltage, high frequency inverters
• Free wheeling diode applications
• Polarity protection circuits

Procurement Notes

Verify the specific suffix 'A0G' against the manufacturer's official datasheet to confirm it denotes the standard DO-41 bulk packaging variant rather than a specialized reel configuration. Ensure the component meets RoHS compliance requirements if mandated by the target assembly process. Cross-reference the part number with the latest Taiwan Semiconductor catalog to confirm active production status and availability.

Selection Notes

Select this component for designs requiring low forward voltage drop and high switching speed in low-voltage environments. The 20 V rating limits suitability to specific low-voltage DC-DC converter topologies. Evaluate thermal management needs based on the 1 A continuous current rating and the thermal resistance characteristics inherent to the DO-41 plastic encapsulation.

Part Context

This component belongs to the standard 1N581x series of Schottky rectifiers, widely utilized in general-purpose power supply applications. The 1N5817 specifically targets low-voltage scenarios where minimizing conduction losses is critical. It serves as a direct replacement for legacy equivalents in existing circuit designs requiring robust surge handling and reliable performance under varying temperature conditions.

Replacement Considerations

Direct substitutes include the 1N5817 manufactured by other vendors such as Diodes Incorporated or Microchip Technology. Verify that alternative sources maintain identical electrical parameters, specifically the 20 V reverse voltage and 1 A forward current ratings, to ensure functional compatibility.
