1N4249US/TR

Overview

The 1N4249US/TR is a single ultrafast recovery rectifier manufactured by Microchip Technology. It features a 1 kV reverse voltage rating and supports a continuous forward current of 1 A. The device exhibits a maximum forward voltage of 1.3 V and a reverse leakage current of 1 uA. Key electrical characteristics include a peak repetitive reverse voltage of 1000 V, a maximum average forward rectified current of 1 A, and a surge current capability of 25 A. The component operates within a temperature range of -65°C to +175°C and utilizes an SQ SMT package.

Feature Summary

Ultrafast and fast recovery rectification performance
High thermal stability for demanding environments
Compact surface-mount packaging

Applications

High-frequency power supply circuits
General-purpose rectification in electronic systems
DC-DC converter output stages

Procurement Notes

Verify the specific suffix TR indicates reel packaging configuration when sourcing. Confirm the SQ SMT footprint compatibility with your PCB design before integration. Ensure the manufacturer designation matches Microchip Technology specifications to guarantee parameter accuracy. Cross-reference datasheet revisions for any updates to mechanical dimensions or electrical limits.

Selection Notes

Select this component for applications requiring rapid switching speeds and high reverse voltage tolerance. The SQ SMT form factor suits space-constrained designs. Evaluate thermal management requirements given the 175°C maximum junction temperature limit. Compare against standard recovery diodes if lower cost is prioritized over speed.
