1N6864US

Overview

The Microchip Technology 1N6864US is a small-signal Schottky rectifier designed for surface-mount applications. It features an 80 V repetitive reverse voltage rating and supports a continuous forward current of 3 A. The device utilizes silicon technology in a D-5B-2 SQ-MELF package. Key electrical characteristics include a maximum forward voltage of 700 mV at rated current and a low reverse leakage current of 150 uA. It withstands an 80 A forward surge current and operates within a junction temperature range of -65°C to +125°C.

Feature Summary

• Schottky barrier construction ensures fast switching speeds and minimal reverse recovery time.
• Low forward voltage drop reduces power dissipation and improves overall system efficiency.
• Hermetically sealed voidless-glass SQ-MELF package provides high reliability and environmental resistance.

Applications

• High-frequency rectification in DC-DC converters
• Power supply input protection circuits
• Clamping diodes in logic interface applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact package variant and testing level. Confirm RoHS compliance status as indicated in the product specifications, noting that certain military-grade variants may not meet standard environmental directives. Ensure the supplier provides valid traceability documentation for hermetically sealed components.

Selection Notes

Select this component when a low-loss, high-reliability Schottky rectifier is required for surface-mount designs. The 80 V rating suits low-voltage power rails, while the 3 A current capacity handles moderate load requirements. Consider the SQ-MELF footprint for space-constrained PCB layouts requiring robust thermal performance.

Part Context

This part belongs to Microchip's industry-recognized series of surface-mount Zener and rectifier diodes. It serves as the SMD equivalent to traditional axial-leaded packages, offering similar electrical performance in a compact form factor suitable for automated assembly processes.

Replacement Considerations

Consult official substitution guides for direct pin-compatible alternatives within the same voltage and current class. Verify that any substitute maintains the SQ-MELF package dimensions and hermetic sealing requirements if used in critical applications.
