1N5260B-TR

Single Zener Diodes Overview

The Vishay 1N5260B-TR is a silicon planar power Zener diode with a nominal voltage of 43 V and ±5% tolerance. It operates in the DO-204AH (DO-35) axial through-hole package, dissipating up to 500 mW at thermal equilibrium. The device features a maximum dynamic resistance of 93 Ω at a test current of 3 mA, with a reverse leakage current of 0.1 μA at 33 V. It supports junction temperatures up to 175 °C and includes a standard cathode identification band.

Single Zener Diodes Feature Summary

• Utilizes silicon planar technology for robust voltage stabilization
• Provides precise regulation with standard ±5% voltage tolerance
• Designed for high thermal stability across extended temperature ranges

Single Zener Diodes Applications

• Voltage stabilization circuits
• Reference voltage generation
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify that the ordering code explicitly contains the 'B' suffix to confirm the required ±5% tolerance specification. Ensure the '-TR' suffix matches the desired reel packaging format. Cross-reference the manufacturer part number against official Vishay documentation to validate authenticity and revision status before procurement.

Single Zener Diodes Selection Notes

Select this component when a stable 43 V reference is required in an axial leaded package. The 500 mW power rating suits low-current applications where higher dissipation is unnecessary. Verify that the 93 Ω dynamic impedance meets the circuit's ripple rejection requirements.

Single Zener Diodes Part Context

This device belongs to the 1N5221 to 1N5267 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide voltage range from 2.4 V to 75 V, providing standardized options for various electronic design needs within the same physical footprint and electrical family.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other manufacturers' 1N5260 equivalents or Vishay variants such as the 1N5260C-TR for tighter tolerance requirements. Ensure any replacement maintains the DO-204AH package dimensions and 500 mW power dissipation capability.
