1N6677/TR

Overview

The Microchip Technology 1N6677-1e3/TR is a small-signal Schottky rectifier designed for surface-mount applications. It features a single diode configuration within a DO-35-2 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 maximum forward voltage drop of 500 mV and a peak forward surge current capability of 5 A. The component operates reliably across a temperature range from -65°C to +125°C and is supplied in a reel packaging format.

Feature Summary

• Schottky barrier construction provides low forward voltage drop and fast switching performance.
• Hermetically sealed hard glass axial-leaded package ensures environmental durability.
• Metallurgically bonded double plug construction enhances mechanical stability.

Applications

• High-frequency signal detection circuits
• Power supply rectification in compact designs
• Clamping and protection diodes in sensitive electronics

Procurement Notes

Verify the specific suffix against official documentation, as variations such as -1 or UR-1 indicate different physical packages or lead configurations. Confirm RoHS compliance status directly with the manufacturer, as commercial versions may differ from military-grade equivalents. Ensure the reel quantity matches production requirements, noting that standard factory pack quantities may vary by region and distributor agreements.

Selection Notes

Select this component when a low-profile surface-mount Schottky diode is required for high-efficiency rectification. Compare the 200 mA current rating against circuit load demands to ensure adequate margin. Evaluate the 40 V reverse voltage limit relative to peak inverse voltages in the application. Consider the DO-35-2 footprint compatibility during PCB layout design to ensure proper soldering and thermal management.

Part Context

This part belongs to the 1N6675 through 1N6677 series of Schottky barrier rectifiers manufactured by Microchip Technology. The series offers various voltage ratings within the same form factor, allowing designers to select appropriate breakdown voltages while maintaining consistent board space requirements. The TR suffix specifically denotes tape-and-reel packaging suitable for automated assembly processes.

Replacement Considerations

Direct substitutes include other 1N6677 variants such as 1N6677-1 or 1N6677UR-1, provided the package type (DO-35 vs DO-35-2) and mounting style are compatible. Verify that alternative Schottky diodes meet the 40 V reverse voltage and 200 mA forward current specifications without compromising thermal performance.
