JAN1N4566A-1/TR

Single Zener Diodes Overview

The JAN1N4566A-1/TR is a temperature-compensated Zener diode manufactured by Microchip Technology. It features a nominal Zener voltage of 6.4V with a power dissipation rating of 0.5W (500mW). The device utilizes a DO-35 (DO-204AH) axial leaded package and operates within a junction temperature range of -65°C to +175°C. Key electrical specifications include a maximum reverse leakage current of 2µA and a Zener impedance of 200 Ohms at a test current of 500µA. This component is designed for high-reliability applications requiring stable voltage regulation under varying thermal conditions.

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against official Microchip documentation to confirm temperature compensation and tolerance levels. Ensure compliance with relevant military or industrial standards required for your application. Confirm availability status as supply chain conditions may vary. Cross-reference the exact part number with authorized distributors to prevent counterfeit components. Review environmental compliance data sheets for RoHS and REACH status prior to integration.

Single Zener Diodes Selection Notes

Select this component when precise voltage stability is critical despite significant temperature fluctuations. The temperature-compensated characteristic distinguishes it from standard Zener diodes, making it ideal for precision references. Consider the DO-35 package size for board space constraints. Evaluate the 500mW power rating against expected circuit loads. Verify that the 6.4V output aligns with system requirements.

Single Zener Diodes Part Context

This part belongs to the JAN series of Zener diodes produced by Microchip Technology, which are typically characterized for high-reliability and harsh environment applications. The JAN designation often implies adherence to stricter quality and screening standards compared to commercial variants. It is part of a broader family of temperature-compensated diodes designed for critical infrastructure and defense electronics where performance consistency is paramount.

Single Zener Diodes Replacement Considerations

Direct substitutes must match the 6.4V Zener voltage, 0.5W power rating, DO-35 package, and temperature-compensated characteristics. Verify equivalent leakage current and impedance specs. Standard non-compensated Zeners are not suitable replacements due to thermal drift differences.
