1N5262C-TR

Single Zener Diodes Overview

The Vishay 1N5262C-TR is a silicon planar power Zener diode in the DO-35 (DO-204AH) axial through-hole package. It provides a nominal Zener voltage of 51 V with a tight ±2 % tolerance, indicated by the 'C' suffix. The device dissipates up to 500 mW at thermal equilibrium and operates within a junction temperature range of -65 °C to +175 °C. Electrical characteristics include a maximum reverse leakage current of 100 nA at 39 V and a typical dynamic resistance of 125 Ω at a test current of 2.5 mA.

Single Zener Diodes Feature Summary

• High precision voltage regulation achieved through a ±2 % Zener voltage tolerance
• Robust thermal performance supporting operation up to a 175 °C junction temperature
• Low leakage current ensures minimal power loss during non-conducting states

Single Zener Diodes Applications

• Voltage stabilization circuits
• Precision reference voltage generation
• Overvoltage protection for sensitive electronic components

Single Zener Diodes Procurement Notes

Verify that the ordering code explicitly includes the 'C' suffix to ensure procurement of the ±2 % tolerance variant rather than the standard ±5 % version. Confirm the '-TR' designation matches the required reel packaging format for automated assembly processes. Cross-reference the document revision date against manufacturing records to ensure compliance with current material categorization standards.

Single Zener Diodes Selection Notes

Select this component when circuit designs demand tighter voltage stability than standard Zener diodes can provide. The 51 V rating suits applications requiring precise mid-range reference levels. Ensure the PCB layout accommodates the DO-35 axial leads and allows sufficient lead length to maintain the specified thermal resistance limits during high-power dissipation scenarios.

Single Zener Diodes Part Context

This part belongs to the Vishay 1N52xxB/C series of small signal Zener diodes. The series covers a wide voltage range from 2.4 V to 75 V. The 'C' suffix specifically denotes the tighter manufacturing tolerance class compared to the standard 'B' suffix devices. These diodes are widely used in general-purpose electronics where reliable voltage clamping is required.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' 1N5262C equivalents or Vishay's own 1N5262B if the looser ±5 % tolerance is acceptable. Verify that any replacement maintains the same DO-35 footprint and meets the 500 mW power dissipation requirement.
