1N5260B/TR

Single Zener Diodes Overview

The Microchip Technology 1N5260B/TR is a Zener Voltage Regulator with a nominal voltage of 43 V and a 5% tolerance. It features a DO-35 (DO-204AH) glass axial-lead package and dissipates up to 500 mW at 25°C. The device operates within a temperature range of -65°C to +175°C, has a maximum reverse current of 100 nA, and a Zener impedance of 93 Ohms.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for through-hole integration
• Includes internal bonds available with specific suffix options

Single Zener Diodes Applications

• Voltage regulation in electronic circuits
• Reference voltage generation
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify the component matches the specified JEDEC type number and electrical parameters against official datasheets. Confirm that the TR suffix indicates tape and reel packaging compliant with EIA-296 standards. Ensure the manufacturer designation aligns with Microsemi or Microchip Technology documentation.

Single Zener Diodes Selection Notes

Select this component when a 43 V Zener diode with 5% tolerance is required. Consider the 500 mW power dissipation limit and the -65°C to +175°C operating temperature range. Verify compatibility with the DO-35 package dimensions and lead configuration for the intended PCB layout.

Single Zener Diodes Part Context

This part belongs to the 1N5221 through 1N5281B series of 0.5 watt Zener Voltage Regulators. The series offers voltages from 2.4 to 200 volts in standard 5% or 10% tolerances. These glass axial-leaded DO-35 Zeners are also available in various military screening levels by adding prefix identifiers.

Single Zener Diodes Replacement Considerations

Consult factory resources for surface mount equivalents in the MLL5221 to MLL5281B series using the DO-213AA MELF style package. DO-7 glass body axial-leaded equivalents are also available as alternatives.
