DSB1A20

Single Diodes Overview

The DSB1A20 is a Schottky barrier rectifier manufactured by Microchip Technology, designed for high-efficiency power conversion applications. It features a maximum average forward rectified current of 1 Ampere and a maximum repetitive peak reverse voltage of 20 Volts. The device utilizes a DO-41 axial through-hole package, ensuring robust mechanical stability for general-purpose mounting. Key electrical characteristics include a low forward voltage drop to minimize conduction losses and fast switching capabilities with a reverse recovery time of less than 500 nanoseconds. The component operates reliably within a junction temperature range from -65°C to +150°C, providing durability in demanding thermal environments.

Single Diodes Procurement Notes

Verify the specific qualification level required for your application, as this component family includes commercial variants alongside MIL-PRF-19500/586 qualified levels such as JAN, JANTX, JANTXV, and JANS. Ensure that the ordering suffix matches the desired reliability grade. Confirm package integrity upon receipt, as axial leads require appropriate handling during insertion. Cross-reference datasheet revisions to ensure compatibility with existing design specifications.

Single Diodes Selection Notes

Select the DSB1A20 when a low-cost, high-reliability Schottky rectifier is needed for low-voltage, moderate-current applications. Its 20V rating suits systems where voltage spikes are minimal. Consider the DO-41 package constraints regarding board space and thermal dissipation compared to surface-mount alternatives. Evaluate the trade-off between the lower forward voltage and potential leakage current increases at elevated temperatures relative to standard silicon diodes.

Single Diodes Part Context

This component belongs to the broader family of 1 Amp Schottky Barrier Rectifiers produced by Microchip Technology. It shares architectural similarities with parts like the 1N5818-1 and 1N6761-1, differing primarily in breakdown voltage ratings. The series is engineered to meet stringent military standards while offering commercial versions for cost-sensitive industrial markets. This lineage ensures consistent manufacturing quality and parameter stability across the product line.

Single Diodes Replacement Considerations

Direct substitutes within the same voltage class include the 1N5817 and 1N5818. For higher voltage requirements, consider the 1N5819 or 1N5820. Verify that replacement components match the DO-41 package dimensions and maintain equivalent current and thermal ratings.
