Overview
The Microchip Technology 1N6620U/TR is a single 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 2 A. The device utilizes the SQ-MELF, A package (D-5A) form factor. Key electrical characteristics include a maximum forward voltage of 1.6 V at 2 A and a typical reverse leakage current of 500 nA at 400 V. The component operates within a junction temperature range of -65°C to 150°C.
Feature Summary
- Fast recovery rectification capability suitable for high-speed switching applications
- Surface-mount construction in a compact SQ-MELF, A package
- High thermal stability with operation up to 150°C junction temperature
Applications
- General-purpose rectification in power supply circuits
- Free-wheeling diodes in inductive load protection
- DC-DC converter output rectification
Procurement Notes
Verify the specific suffix against official documentation, as variations exist between US and U designations. Confirm RoHS compliance status, as standard variants may not meet current environmental directives. Validate package dimensions and pinout compatibility during integration. Ensure ordering quantities align with manufacturer reel specifications. Cross-reference datasheet revisions to confirm parameter consistency.
Selection Notes
Select this component when a 2 A current rating and 200 V blocking voltage are required in a surface-mount footprint. Consider the fast recovery characteristic for efficiency in higher frequency applications. Evaluate thermal management requirements given the 150°C maximum junction limit. Compare physical dimensions against available PCB real estate constraints.
Part Context
This part belongs to the 1N6620 series of fast recovery rectifiers manufactured by Microchip Technology. The series offers various voltage ratings and packaging options to suit different circuit requirements. The 1N6620 variant specifically targets low-voltage, medium-current applications requiring rapid switching performance.
Replacement Considerations
Consult official substitution lists for verified equivalents. Generic replacements must match the 2 A current, 200 V voltage, and D-5A package constraints.
