1N5259C-TR

Single Zener Diodes Overview

The Vishay 1N5259C-TR is a silicon planar power Zener diode in the DO-35 (DO-204AH) axial leaded package. It provides a nominal Zener voltage of 39 V with a tight tolerance of ±2%, indicated by the 'C' suffix. The device operates at a test current of 3.2 mA and dissipates up to 500 mW. Key electrical parameters include a maximum reverse leakage current of 0.1 µA, a dynamic resistance of 80 Ω, and a typical temperature coefficient of 0.094 %/K. It supports junction temperatures up to 175 °C.

Single Zener Diodes Feature Summary

• High precision voltage regulation with ±2% tolerance
• Robust thermal stability for high-temperature environments
• Low leakage current characteristics

Single Zener Diodes Applications

• Voltage stabilization circuits
• Precision reference voltage generation
• Over-voltage protection systems

Single Zener Diodes Procurement Notes

Verify that the ordering code explicitly includes the 'C' suffix to ensure the component meets the required ±2% Zener voltage tolerance specification. Confirm the package type matches the DO-35 form factor and validate compliance with RoHS directives before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when circuit designs demand tighter voltage accuracy than standard ±5% tolerances allow. The low leakage current and defined temperature coefficient make it suitable for applications requiring stable reference voltages across varying thermal conditions.

Single Zener Diodes Part Context

This part belongs to the Vishay 1N5221 to 1N5267 series of small signal Zener diodes. The series covers a wide range of nominal voltages from 2.4 V to 75 V. The 'C' suffix variant specifically denotes the tighter manufacturing tolerance compared to the standard 'B' suffix devices within the same family.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other manufacturers' 1N5259C equivalents or Vishay's own 1N5259B-TR if the looser ±5% tolerance is acceptable for the application.

Single Zener Diodes FAQ

What does the 'C' suffix indicate in the 1N5259C-TR model?

The 'C' suffix indicates a Zener voltage tolerance of ±2%, which is tighter than the standard ±5% tolerance found in 'B' suffix versions.

What is the maximum operating junction temperature?

The maximum operating junction temperature is 175 °C.
