Overview
The Microchip Technology 1N6627US/TR is a single fast recovery rectifier diode designed for surface-mount applications. It features a maximum repetitive peak reverse voltage of 400 V and an average forward current rating of 4 A. The device exhibits a typical reverse recovery time of 45 ns with a maximum forward voltage drop of 1.5 V at the rated current. It operates within a junction temperature range of -65°C to +150°C and is housed in an E-Package-2 (SQ-MELF) leadless package.
Feature Summary
- Fast recovery performance suitable for high-frequency switching applications
- Leadless SQ-MELF surface-mount package design
- Extended thermal operating range up to 150°C
Applications
- High-frequency power supply circuits
- Free-wheeling rectification in DC-DC converters

Procurement Notes
Verify the specific suffix configuration against official Microchip documentation to confirm pinout and electrical tolerances. Confirm RoHS compliance status as indicated in the datasheet, noting that military variants may differ. Ensure the ordering quantity aligns with the manufacturer's standard reel packaging requirements.
Selection Notes
Select this component when a 400 V blocking capability and 4 A continuous current are required in a compact surface-mount form factor. The 45 ns recovery time makes it appropriate for frequencies exceeding standard general-purpose diodes. Evaluate thermal management needs given the leadless package construction and high-temperature rating.
Part Context
