Overview
The Microchip Technology 1N6700US/TR is a surface-mount Schottky barrier rectifier designed for high-efficiency power conversion. It features a D-5C (SQ-MELF) package, enabling compact circuit layouts. The device offers a maximum repetitive peak reverse voltage of 20 V and an average forward rectified current of 5 A. Key electrical characteristics include a low forward voltage drop to minimize conduction losses and a fast switching speed with negligible reverse recovery time. Operating temperatures range from -55 °C to +175 °C, ensuring reliability in demanding thermal environments.
Feature Summary
- Schottky barrier technology provides ultra-fast switching speeds and minimal reverse recovery charge.
- Low forward voltage drop reduces power dissipation and improves overall system efficiency.
- Robust SQ-MELF (D-5C) surface-mount package supports automated assembly and high-density PCB designs.
- Extended junction temperature rating ensures stable operation under elevated thermal stress conditions.
Applications
- High-frequency DC-DC converter output rectification
- Free-wheeling diodes in synchronous rectifier circuits
- Power supply input protection against reverse polarity
- Clamping diodes in logic interface circuits
Procurement Notes
Verify the specific suffix designation to confirm tape-and-reel packaging configuration. Ensure compatibility with standard SMD reflow soldering profiles. Confirm RoHS compliance status matches project requirements. Validate that the D-5C footprint aligns with existing PCB silkscreen and copper pad designs before finalizing procurement orders.
Selection Notes
Select this component when low forward voltage and fast recovery are critical for efficiency. The 5 A current rating suits moderate-power applications requiring compact form factors. Consider the 20 V reverse voltage limit for low-voltage systems. Evaluate thermal management needs given the small package size and high current capability.
Part Context
This part belongs to Microchip's legacy 1N series adapted for modern surface-mount manufacturing. It replaces through-hole equivalents in space-constrained designs. The SQ-MELF package offers improved mechanical stability compared to axial leads while maintaining similar electrical performance characteristics for general-purpose rectification tasks.
Replacement Considerations
Direct replacements must match the 20 V / 5 A rating and D-5C package. Verify equivalent forward voltage and reverse leakage specifications. Cross-reference pinout compatibility if substituting with different manufacturers' Schottky diodes in the same footprint.
