1N5263/TR

Single Zener Diodes Overview

The Microchip Technology 1N5263/TR is a silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 56 V with a tolerance of 20%. The device has a maximum power dissipation of 0.417 W and operates within a temperature range of -65°C to +175°C junction temperature. It utilizes a DO-7 (DO-204AA) glass axial-lead package with two terminals. Key electrical characteristics include a maximum reverse leakage current of 100 nA at 43 V, a Zener impedance of 150 ohms, and a test current of 2.2 mA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation using a single unidirectional silicon Zener junction.
• Constructed in a hermetically sealed glass axial-lead package suitable for harsh environments.
• Capable of operation across an extended industrial and military-grade temperature range.

Single Zener Diodes Applications

• Voltage reference circuits requiring stable DC levels.
• Overvoltage protection stages in electronic systems.
• Clamping applications for transient voltage suppression.

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against official Microchip documentation to ensure correct tolerance and screening level. Confirm package compatibility with PCB layout requirements. Check for RoHS compliance status as historical variants may differ. Validate that the supplier provides genuine components with traceable manufacturing data.

Single Zener Diodes Selection Notes

Select this component when a 56 V regulation point is required in a through-hole axial package. Consider the 20% voltage tolerance for circuit design margins. Ensure the 0.417 W power rating suffices for the expected operating conditions. Evaluate the high-temperature capability for demanding operational environments.

Single Zener Diodes Part Context

This part belongs to the standard 1N52xx series of Zener diodes manufactured by Microchip Technology. The series offers a wide range of voltage values in both axial leaded and surface mount packages. The 1N5263 variant specifically targets the 56 V segment of this portfolio.

Single Zener Diodes Replacement Considerations

Consult official Microchip substitution guides for verified equivalents. Generic cross-references may not match the specific hermetic sealing or temperature ratings. Verify pinout and package dimensions before implementation.
