1N6628US

Overview

The Microchip Technology 1N6628US is a surface-mount ultrafast recovery rectifier diode designed for high-reliability applications. It features a glass passivated junction and operates with a maximum repetitive peak reverse voltage of 600 V. The device supports an average forward rectified current of 1.5 A and is housed in the D-5B-2 SQ-MELF package.

Feature Summary

• Ultrafast recovery characteristics suitable for high-frequency switching
• Hermetically sealed glass construction for environmental stability
• High thermal shock resistance capability

Applications

• High-reliability power supply circuits
• Free-wheeling rectification in inductive loads
• DC-DC converter output stages

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm exact electrical tolerances and testing standards. Ensure compatibility with MIL-PRF-19500/585 requirements if military qualification is mandated. Confirm RoHS status as standard versions may not comply with modern environmental directives.

Selection Notes

Select this component when ultrafast recovery times are critical for minimizing switching losses. The D-5B-2 package offers robust mechanical stability for surface mount assembly. Evaluate thermal management needs based on the 1.5 A continuous current rating and junction temperature limits.

Part Context

This part belongs to the 1N662xUS series of voidless hermetically sealed surface mount ultrafast recovery glass rectifiers. These components are engineered for environments where failure is not an option, providing superior performance over standard silicon rectifiers in demanding power electronics applications.

Replacement Considerations

Direct substitutes include JAN1N6628US or JANTXV1N6628US for enhanced military-grade screening. Verify pinout and package dimensions match the D-5B-2 form factor before integration.
