Overview
The Microchip Technology 1N6864US is a silicon small-signal Schottky rectifier designed for through-hole mounting in the D-5B-2 package. It features a single diode configuration with an 80 V repetitive reverse voltage rating and a 3 A average forward current capability. The device exhibits a low forward voltage of 700 mV at rated current and supports an 80 A non-repetitive forward surge current. Operating reliably across a temperature range from -65°C to +125°C, it maintains a maximum reverse leakage current of 150 µA.
Feature Summary
- Utilizes silicon Schottky technology to achieve low forward voltage drop and high switching efficiency.
- Engineered for robust performance under high thermal stress with extended operating temperature limits.
- Provides reliable protection against transient overcurrent events through high surge current handling.
Applications
- High-frequency power supply rectification
- Free-wheeling diodes in DC-DC converters
- Reverse polarity protection circuits
Procurement Notes
Verify the specific suffix (e.g., US) when ordering, as it denotes the SQ-MELF surface mount package variant. Confirm RoHS compliance status, as this component may be classified as non-compliant depending on the manufacturing date code. Ensure the procurement documentation matches the exact part number to avoid confusion with standard axial lead equivalents.
Selection Notes
Select this component for applications requiring low forward voltage drop and fast recovery characteristics. The 80 V rating suits low-voltage DC systems, while the 3 A current capacity supports moderate power loads. Verify that the circuit design accommodates the specified surge current limits and operates within the defined thermal envelope.
Part Context
This component belongs to Microchip's discrete semiconductor portfolio, specifically within the Schottky diodes and rectifiers category. It serves as a specialized solution for efficient power conversion in compact electronic designs, leveraging silicon technology for reliability in demanding environments.
Replacement Considerations
Cross-reference with other 80V 3A Schottky rectifiers in similar packages. Verify pinout compatibility and thermal resistance specifications before substituting. Ensure the alternative device meets or exceeds the original forward voltage and leakage current requirements.
