1N5263A/TR

Single Zener Diodes Overview

The Microchip Technology 1N5263A/TR is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 56V with a tolerance of 10%. The device has a maximum power dissipation of 0.48W and is housed in a hermetically sealed glass DO-35 axial leaded package (JEDEC DO-204AH). It operates within a temperature range suitable for standard through-hole mounting.

Single Zener Diodes Feature Summary

• Hermetically sealed glass construction for environmental protection
• Axial-leaded DO-35 package design for through-hole integration
• Single unidirectional Zener configuration

Single Zener Diodes Applications

• Voltage regulation circuits
• Reference voltage generation
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging, distinct from bulk variants like the 1N5263A. Confirm RoHS compliance status as the base part may be non-compliant. Ensure the 10% tolerance aligns with circuit requirements rather than tighter military grades.

Single Zener Diodes Selection Notes

Select this component when a 56V regulation point is required in a standard DO-35 footprint. Consider the 0.48W power rating against thermal constraints. Compare against the 1N5263BUR-1 if surface mount DO-213AA placement is necessary instead of axial leads.

Single Zener Diodes Part Context

This part belongs to the 1N5221 through 1N5281 series of 0.5W Zener diodes manufactured by Microsemi/Microchip. The series covers a wide voltage range from 2.4V to 200V. The 1N5263A variant specifically targets the 56V segment within this legacy axial leaded product line.

Single Zener Diodes Replacement Considerations

The 1N5263BUR-1 serves as a parameter-equivalent surface mount alternative in the DO-213AA package.
