1N5802/TR

Overview

The Microchip Technology 1N5802/TR is a single fast recovery rectifier designed for through-hole mounting in an A-Package-2 (DO-41) configuration. It features a maximum repetitive reverse voltage of 50 V and supports an average forward current of 2.5 A with a peak surge current capacity of 35 A. The device exhibits a low forward voltage drop of 975 mV at rated current and a rapid reverse recovery time of 25 ns, ensuring efficient switching performance. Operating reliably across a wide temperature range from -65 °C to +175 °C junction temperature, it maintains a low reverse leakage current of 1 uA.

Feature Summary

• Fast recovery characteristics enable high-speed switching applications with minimal reverse recovery charge.
• Robust thermal stability allows reliable operation in extreme environments up to 175 °C junction temperature.
• High surge current capability provides protection against transient overloads during power-up or fault conditions.

Applications

• High-frequency DC-DC converter circuits requiring fast switching diodes
• Free-wheeling rectification in inductive load drive systems
• Clamping and flyback protection in automotive electronic control units

Procurement Notes

Verify the specific suffix /TR indicates tape-and-reel packaging upon order confirmation. Confirm RoHS compliance status as non-compliant data suggests restricted material usage. Validate that the A-Package-2 footprint matches your PCB design requirements before finalizing procurement. Ensure supply chain sources provide official Microchip documentation to guarantee authenticity and traceability.

Selection Notes

Select this component when a through-hole fast recovery diode with 50 V blocking voltage is required. Compare the 25 ns recovery time against slower standard recovery alternatives if switching losses are critical. Consider the 2.5 A continuous current rating relative to your circuit's thermal dissipation capabilities. Verify compatibility with existing board layouts utilizing the DO-41 package style.

Part Context

This part belongs to the 1N58xx series of fast recovery rectifiers manufactured by Microchip Technology. It serves as a specialized semiconductor solution for power conversion applications where speed and reliability are paramount. The device complements other rectifier offerings in the portfolio by providing optimized performance for high-frequency switching environments.

Replacement Considerations

Consult official Microchip substitution guides for verified equivalents. Generic replacements may not match the specific 25 ns recovery time or 175 °C thermal rating. Verify pinout compatibility and package dimensions before integrating alternative components into the design.
