Overview
The Microchip Technology 1N6628/TR is a single fast recovery rectifier designed for surface-mount applications. It features a maximum repetitive peak reverse voltage of 600 V and an average forward rectified current of 2.3 A. The device exhibits a typical forward voltage drop of 1.5 V at 4 A and a maximum reverse leakage current of 2 µA at 600 V. Key electrical characteristics include a reverse recovery time of 45 ns, a junction-to-case thermal resistance suitable for high-temperature operation up to +150 °C, and a minimum operating temperature of -65 °C. The component is housed in the D-5B (SQ-MELF) package.
Feature Summary
- Fast recovery performance with a 45 ns reverse recovery time
- High-temperature capability with a junction range from -65 °C to +150 °C
- Surface-mount construction in a compact SQ-MELF package
Applications
- High-frequency power supply circuits
- Free-wheeling diode applications in DC-DC converters
- Snubber circuits requiring fast switching characteristics
Procurement Notes
Verify the specific suffix configuration against official Microchip documentation to ensure correct packaging and lead times. Confirm RoHS compliance status as indicated in the datasheet, noting that standard versions may not be compliant. Validate the manufacturer part number directly with authorized distributors to avoid counterfeit components and ensure traceability.
Selection Notes
Select this component when a surface-mount fast recovery rectifier with 600 V blocking capability is required. Ensure the circuit design accommodates the 2.3 A average current rating and the thermal constraints of the D-5B package. Compare specifications against through-hole alternatives if board space allows, considering the trade-off between mounting style and thermal performance.
Part Context
This part belongs to the 1N6628 series of fast recovery rectifiers manufactured by Microchip Technology. The series includes variants with different voltage ratings and packages, such as the 1N6628US/TR for surface mount and JANTX1N6628/TR for military-grade through-hole applications. The 1N6628/TR specifically denotes the surface-mount version in the D-5B package.
