1N5253C-TR

Single Zener Diodes Overview

The Vishay 1N5253C-TR is a silicon planar power Zener diode in the 1N5221 to 1N5267 series, housed in a DO-35 (DO-204AH) axial lead package. It provides a nominal Zener voltage of 25 V with a tight ±2% tolerance, indicated by the 'C' suffix. The device operates at a test current of 5 mA and dissipates up to 500 mW of power. Key electrical characteristics include a maximum reverse leakage current of 0.1 µA at 23 V, a typical dynamic resistance of 35 Ω, and a temperature coefficient of 0.089 %/K.

Single Zener Diodes Feature Summary

• High precision voltage regulation achieved through a standard ±2% Zener voltage tolerance
• Robust thermal performance supported by a junction temperature rating up to 175 °C
• Low leakage current ensures minimal power loss when operating below the breakdown threshold

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify that the ordering code explicitly includes the 'C' suffix to confirm the required ±2% tolerance specification. Ensure the procurement documentation specifies the '-TR' suffix for reel packaging. Confirm compliance with material categorization definitions via the manufacturer's official documentation before finalizing orders.

Single Zener Diodes Selection Notes

Select this component when circuit designs demand tighter voltage accuracy than standard ±5% tolerances allow. The DO-35 package supports through-hole mounting, making it suitable for general-purpose boards requiring robust axial leads. Evaluate the 500 mW power dissipation limit against expected thermal conditions to ensure safe operation within the specified junction temperature range.

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 voltage range from 2.4 V to 75 V, utilizing silicon planar technology. The specific 1N5253 variant targets applications requiring a stable 25 V reference point with high manufacturing consistency.

Single Zener Diodes Replacement Considerations

Cross-reference other manufacturers offering 25 V Zener diodes in the DO-35 package. Verify that alternative parts match the ±2% tolerance requirement and maintain equivalent power dissipation and thermal resistance ratings to ensure functional compatibility.
