1N5816

Overview

The Microchip Technology 1N5816 is a small-signal Schottky rectifier designed for through-hole mounting in the DO-204AL (DO-41) axial leaded package. It features a maximum repetitive peak reverse voltage of 20 V and an average forward rectified current rating of 1 A. The device utilizes silicon technology to achieve a low forward voltage drop, typically 1 V at 1 A, while maintaining a low reverse leakage current of 1 mA at 30 V. It supports a high non-repetitive peak forward surge current of 50 A and operates reliably within a junction temperature range of -55°C to +150°C.

Feature Summary

• Schottky barrier construction provides fast switching characteristics with minimal reverse recovery time.
• Low forward voltage drop reduces power dissipation and improves overall system efficiency.
• High thermal stability allows reliable operation across a wide junction temperature range.
• Through-hole axial packaging facilitates easy integration into standard printed circuit board layouts.

Applications

• Power supply input rectification
• Free-wheeling diodes in DC-DC converters
• Polarity protection circuits
• Clamping diodes in logic interfaces

Procurement Notes

Verify the specific ordering suffix and manufacturing date code upon request, as production lots may vary. Confirm RoHS compliance status directly with the manufacturer or authorized distributor, as regulatory declarations can change over time. Ensure the procurement channel is authorized to guarantee component authenticity and traceability. Check for any recent Product Change Notifications that might affect pinout or material composition before finalizing orders.

Selection Notes

Select this component when a low forward voltage drop and fast switching speed are required in a through-hole application. The 20 V reverse voltage rating suits low-voltage DC systems. Compare against similar Schottky diodes if higher current capacity or different package constraints exist. Verify that the 1 A average current rating meets the continuous load requirements of the target circuit design.

Part Context

The 1N5816 belongs to the widely recognized 1N58xx series of Schottky rectifiers produced by Microchip Technology. This series is established for general-purpose rectification where low loss and high efficiency are priorities. The part shares functional similarities with other industry-standard equivalents but offers specific performance characteristics defined by Microchip's manufacturing processes and quality standards.

Replacement Considerations

Cross-reference with other 1N5816 variants from different manufacturers to ensure pin compatibility and electrical equivalence. Verify that substitute parts meet the same 20 V reverse voltage and 1 A current ratings. Check for differences in forward voltage specifications and package dimensions to confirm fitment in existing assemblies.
