1N5621US/TR

Overview

The Microchip Technology 1N5621US/TR is a single fast recovery rectifier diode designed for surface-mount applications. It features an A-Package-2 form factor with a maximum repetitive reverse voltage of 800 V and an average forward current rating of 1 A. The device exhibits a forward voltage drop of 1.6 V at rated current and supports a maximum surge current of 25 A. Key electrical characteristics include a reverse leakage current of 500 nA and a typical reverse recovery time of 300 ns. It operates within a junction temperature range of -65 °C to +175 °C.

Feature Summary

Fast recovery performance suitable for high-frequency switching applications
High thermal stability with extended operating temperature range up to 175 °C
Surface-mount construction in compact A-Package-2 configuration

Applications

High-frequency power supply circuits
Free-wheeling rectification in DC-DC converters
Snubber circuits in switching mode power supplies

Procurement Notes

Verify the specific suffix TR indicates tape-and-reel packaging when ordering. Confirm RoHS status as non-compliant based on available documentation. Ensure compatibility with standard SMD assembly processes for the A-Package-2 footprint. Validate that the 800V rating meets circuit requirements before integration.

Selection Notes

Select this component for designs requiring fast recovery characteristics in a surface-mount package. Compare against standard recovery alternatives if lower cost is prioritized over speed. Ensure the 1A current rating aligns with peak load demands. Consider the 175°C max junction temperature for high-thermal environments.

Part Context

This part belongs to the 1N56xx series of rectifiers manufactured by Microchip Technology. It serves as the surface-mount equivalent to through-hole variants like the 1N5621. The US suffix typically denotes the small outline package style, distinguishing it from axial leaded versions while maintaining similar electrical specifications.
