Overview
The Microchip Technology 1N6626US/TR is a single ultra-fast recovery rectifier designed for surface-mount applications. It features a maximum repetitive peak reverse voltage of 200 V and an average forward rectified current of 4 A. The device exhibits a fast recovery time of 30 ns with a maximum forward voltage drop of 1.5 V at rated current. It operates within a junction temperature range of -65°C to +150°C and is housed in the D-5B-2 package.
Feature Summary
- Ultra-fast recovery characteristics enable efficient switching performance
- High thermal stability supports operation up to 150°C junction temperature
- Robust surge current handling capability for transient protection
Applications
- High-frequency power supply circuits
- Free-wheeling diode applications in motor drives
- Snubber circuits in switching mode power supplies
Procurement Notes
Verify the specific suffix US/TR against official Microchip documentation to confirm the surface-mount D-5B-2 package and tape-and-reel delivery format. Ensure compatibility with RoHS directives if required by your system specifications, as standard variants may differ from lead-free versions. Cross-reference the part number with authorized distributors to validate authenticity and traceability.
Selection Notes
Select this component when a high-current (4A) ultra-fast recovery diode is required in a compact surface-mount footprint. Compare the 30 ns recovery time against alternative parts to ensure it meets the switching frequency requirements of the target circuit. Verify that the 200 V reverse voltage rating provides sufficient margin for the peak inverse voltage present in the application environment.
Part Context
This component belongs to the 1N662x series of ultra-fast recovery rectifiers manufactured by Microchip Technology. The series offers various voltage ratings while maintaining consistent current handling and package styles. The US/TR designation specifically identifies the surface-mount variant supplied in tape and reel packaging for automated assembly processes.
Replacement Considerations
Consult official substitution guides for equivalent ultra-fast recovery rectifiers with matching 4A current and 200V voltage ratings. Verify pinout compatibility and thermal resistance values before replacing the original component in existing designs.
