JANS1N4581AUR-1

Single Zener Diodes Overview

The JANS1N4581AUR-1 is a temperature-compensated Zener diode manufactured by Microchip Technology. It features a nominal Zener voltage of 6.4 V with a tight tolerance of ±0.5%. The device is designed for surface-mount applications in the DO-213AA (SMB) package and has a maximum power dissipation rating of 500 mW. It exhibits low leakage current characteristics, typically specified at 2 µA. This component utilizes silicon as the diode element material and is configured as a single diode.

Single Zener Diodes Feature Summary

• Temperature compensated design for stable voltage reference performance across varying thermal conditions
• High precision voltage tolerance of ±0.5% ensuring accurate regulation
• Surface-mount construction in DO-213AA package for compact circuit integration

Single Zener Diodes Applications

• Low-power regulation stages in electronic systems
• Temperature-compensated biasing networks

Single Zener Diodes Procurement Notes

Verify that the specific part number includes the JANS prefix, which indicates a specialized qualification level distinct from standard commercial variants. Confirm the package type is DO-213AA and ensure the required tolerance matches the ±0.5% specification. Cross-reference manufacturer documentation to confirm active status and availability constraints before finalizing procurement plans.

Single Zener Diodes Selection Notes

Select this component when a stable 6.4 V reference is needed in a surface-mount form factor. The temperature compensation feature makes it suitable for environments where voltage drift due to heat is a concern. Ensure the circuit design can accommodate the 500 mW power dissipation limit and verify that the ±0.5% tolerance meets the system's accuracy requirements compared to standard Zener alternatives.

Single Zener Diodes Part Context

This component belongs to the 1N4581 series of Zener diodes produced by Microchip Technology. It serves as a high-precision variant within the company's diode portfolio, specifically engineered for applications demanding strict voltage stability. The JANS designation often implies adherence to specific reliability standards or environmental qualifications beyond standard commercial offerings.

Single Zener Diodes Replacement Considerations

Direct substitutes may include other temperature-compensated Zener diodes with a 6.4 V nominal voltage and similar power ratings. Verify pinout compatibility for the DO-213AA package. Consider parts with equivalent ±0.5% tolerance if precise voltage regulation is critical. Standard 1N4581 equivalents may lack the specific temperature compensation or tolerance levels required.
