Overview
The JAN1N6840U3 is a silicon Schottky barrier rectifier manufactured by Microchip Technology. It features a low-profile ceramic surface-mount package designed for high-reliability applications. The device provides a reverse voltage rating of 35V and supports a forward current of 0.5A. Key electrical characteristics include a maximum DC blocking voltage of 35V, a forward voltage drop of 0.45V at 0.5A, and a low reverse leakage current of 25µA at rated voltage. Operating temperatures range from -65°C to +175°C junction temperature.
Feature Summary
- Utilizes Schottky barrier technology for ultra-fast switching speeds and minimal recovery charge.
- Constructed with a hermetically sealed low-profile ceramic package for environmental protection.
- Engineered for high thermal stability and reliability in demanding operational environments.
Applications
- High-frequency power supply rectification
- Free-wheeling diodes in DC-DC converters
- Protection circuits in aerospace and military systems
Procurement Notes
Verify the specific suffix U3 against the manufacturer's latest datasheet to confirm package dimensions and marking codes. Ensure compliance with RoHS directives if required by the end application. Confirm moisture sensitivity levels and recommended reflow profiles prior to assembly. Request batch-specific test reports for critical reliability requirements.
Selection Notes
Select this component when low forward voltage drop and fast switching are prioritized over higher voltage ratings. Compare total power dissipation capabilities against system thermal constraints. Verify that the ceramic package size fits within the available PCB real estate. Consider the operating temperature range to ensure performance stability under extreme conditions.
Part Context
This part belongs to the JAN1N6840 series of Schottky rectifiers. It is distinct from standard PN-junction diodes due to its metal-semiconductor junction construction. The U3 suffix typically denotes a specific surface-mount ceramic variant within the broader 1N6840 family.
Replacement Considerations
Direct replacements must match the 35V reverse voltage and 0.5A forward current ratings. Verify pinout compatibility and package footprint equivalence. Check for equivalent reverse leakage and forward voltage specifications to maintain circuit performance.
