1N5267C-TR

Single Zener Diodes Overview

The Vishay 1N5267C-TR is a silicon planar power Zener diode in the DO-35 (DO-204AH) axial package. It provides a nominal Zener voltage of 75 V with a tight tolerance of ±2%. The device operates at a test current of 1.7 mA and dissipates up to 500 mW. Key electrical parameters include a maximum reverse leakage current of 0.1 µA, a typical dynamic resistance of 270 Ω, and a temperature coefficient of 0.098 %/K.

Single Zener Diodes Feature Summary

• High precision voltage regulation with ±2% tolerance
• Silicon planar construction for reliability
• Single circuit configuration

Single Zener Diodes Applications

• Voltage stabilization
• Reference voltage generation
• Overvoltage protection circuits

Single Zener Diodes Procurement Notes

Verify that the ordering code includes the 'C' suffix to confirm the ±2% tolerance specification. Ensure the '-TR' suffix matches the required reel packaging format. Cross-reference the document number 85588 for the latest technical specifications and compliance details before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when precise voltage regulation is critical due to its tighter ±2% tolerance compared to standard variants. The 75 V rating suits applications requiring higher reference voltages within the small signal range. Verify thermal management requirements as the 500 mW dissipation limit depends on lead length and ambient conditions.

Single Zener Diodes Part Context

This part 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. The 1N5267 variant specifically targets the upper end of this range, offering stable performance in the high-voltage segment of the family.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' 1N5267B or 1N5267C equivalents in the DO-35 package. Ensure replacement parts match the 75 V nominal voltage and verify if the ±2% tolerance is required or if ±5% is acceptable.
