1N6677UR-1/TR

Overview

The Microchip Technology 1N6677UR-1/TR is a small-signal Schottky rectifier designed for surface-mount applications. It features a single diode configuration within a DO-35 package, utilizing silicon technology. The device supports a maximum repetitive reverse voltage of 40 V and an average forward current rating of 200 mA. Key electrical characteristics include a forward voltage of 700 mV at the rated current and a peak forward surge current capability of 5 A. The component operates reliably across a temperature range from -65°C to +150°C junction temperature.

Feature Summary

• Schottky barrier construction provides low forward voltage drop and fast switching performance suitable for high-frequency applications.
• Surface-mount design in a compact DO-35 package facilitates automated assembly and space-constrained circuit layouts.
• Wide operating temperature range ensures stable functionality in extreme thermal environments.

Applications

• High-frequency signal detection and mixing circuits
• Power supply rectification in low-voltage DC systems
• Clamping and protection diodes in sensitive electronic interfaces

Procurement Notes

Verify the specific suffix designation against official Microchip documentation to confirm tape-and-reel packaging and RoHS compliance status. Ensure the ordering quantity aligns with manufacturer minimum order requirements for reel-based distribution. Cross-reference the complete part number with authorized distributors to validate authenticity and traceability before procurement.

Selection Notes

Select this component when a surface-mount Schottky rectifier is required for low-voltage, high-speed applications. Compare the 700 mV forward voltage specification against alternative packages to ensure compatibility with system power loss constraints. Confirm that the DO-35 footprint matches the PCB layout requirements and that the 40 V reverse voltage rating exceeds the maximum circuit operating voltage.

Part Context

This part belongs to the 1N6677 series of Schottky barrier rectifiers manufactured by Microchip Technology. While the standard 1N6677-1 utilizes an axial-leaded DO-35 package, the UR-1 variant adapts this technology for surface-mount integration. The series is recognized for its reliability in commercial and industrial semiconductor applications requiring efficient rectification.

Replacement Considerations

Consult Microchip datasheets for direct equivalents within the 1N667x series. Verify pinout compatibility and thermal characteristics when substituting with other manufacturers' DO-35 SMD Schottky diodes. Ensure replacement parts meet the same 40 V reverse voltage and 200 mA forward current specifications.
