1N5254B-1

Single Zener Diodes Overview

The Microchip Technology 1N5254B-1 is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 27 V with a tolerance of ±5%. The device operates in a DO-35 axial through-hole package and dissipates up to 500 mW of power. Key electrical characteristics include a maximum reverse leakage current of 100 nA, a Zener impedance of 41 Ohms, and a test current of 4.6 mA. It maintains functionality across an operating temperature range from -65°C to +200°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation at a nominal 27 V level
• Capable of handling 500 mW power dissipation in a compact form factor
• Ensures low leakage current for efficient circuit performance

Single Zener Diodes Applications

• General-purpose voltage regulation tasks

Single Zener Diodes Procurement Notes

Verify the specific suffix designation during procurement, as variations such as 'A' or 'BUR-1' indicate different tolerances or packages. Confirm that the required component matches the standard DO-35 axial leaded configuration rather than surface mount alternatives. Ensure the selected part meets the necessary thermal and electrical specifications for the intended application environment before finalizing orders.

Single Zener Diodes Selection Notes

Select this component when a 27 V regulation point is required with moderate precision. Consider the DO-35 package constraints for board space and mounting style. Evaluate the thermal management requirements against the 500 mW dissipation limit. Compare the Zener impedance and leakage specifications against other available options to ensure compatibility with sensitive downstream circuitry.

Single Zener Diodes Part Context

This component belongs to the 1N52xx series of Zener diodes manufactured by Microchip Technology. The series offers various voltage ratings within a standardized package format. The 1N5254B-1 variant specifically targets applications needing a 27 V breakdown voltage with tighter tolerance compared to non-suffixed versions.

Single Zener Diodes Replacement Considerations

Direct substitutes include the 1N5254A for looser tolerance requirements or the 1N5254BUR-1 for surface mount implementations. Verify pinout compatibility and thermal characteristics when transitioning between axial and SMD variants.
