Overview
The Microchip Technology 1N6628 is a single fast recovery rectifier designed for surface-mount applications. It features a maximum repetitive reverse voltage of 600 V and an average forward rectified current of 3.5 A. The device exhibits a typical forward voltage drop of 1.5 V at rated current and a maximum reverse leakage current of 2 µA. Key electrical characteristics include a peak non-repetitive surge current capability of 75 A and a fast recovery time of 45 ns. It operates within a junction temperature range of -65 °C to +150 °C.
Feature Summary
- Fast recovery performance with a 45 ns switching time suitable for high-frequency circuits
- Surface-mount construction in a D-5B-2 package for automated assembly
- High thermal stability supporting operation up to +150 °C junction temperature
Applications
- High-frequency power supply rectification
- Free-wheeling diodes in DC-DC converters
- Snubber circuits in switching mode power supplies
Procurement Notes
Verify the specific suffix (e.g., /TR) against the datasheet to confirm tape-and-reel packaging requirements. Confirm RoHS compliance status as standard variants may not meet environmental directives. Validate that the D-5B-2 package dimensions match the target PCB footprint before finalizing procurement orders.
Selection Notes
Select this component when a surface-mount fast recovery rectifier is required for 600 V blocking applications. Ensure the design accounts for the 3.5 A continuous current rating and the 75 A surge capability during startup or fault conditions. Verify that the 45 ns recovery time meets the system's switching frequency requirements without excessive reverse recovery charge losses.
Part Context
This part belongs to the 1N66xx series of fast recovery rectifiers manufactured by Microchip Technology. It serves as a surface-mount alternative to through-hole axial leaded packages, offering similar electrical performance in a compact form factor. The series is engineered for general-purpose rectification in demanding electronic environments requiring reliable high-speed switching.
Replacement Considerations
Cross-reference with JANTX1N6628/TR for military-grade specifications. Verify pinout compatibility with other D-5B-2 packaged rectifiers from different manufacturers before substitution.
