1N5266C-TR

Single Zener Diodes Overview

The Vishay 1N5266C-TR is a silicon planar power Zener diode in the 1N5221 to 1N5267 series, housed in a DO-35 (DO-204AH) axial leaded package. It features a nominal Zener voltage of 68 V with a tight ±2% tolerance indicated by the 'C' suffix. The device operates at a test current of 1.8 mA and dissipates up to 500 mW at thermal equilibrium. Key electrical characteristics include a maximum reverse leakage current of 0.1 µA at 25 V, a typical dynamic resistance of 230 Ω at the test current, and a temperature coefficient of 0.097 %/K.

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
• Standardized DO-35 axial leaded package for reliable through-hole mounting

Single Zener Diodes Applications

• Voltage stabilization circuits
• Precision reference voltage generation
• Overvoltage protection stages

Single Zener Diodes Procurement Notes

Verify the specific ordering code matches the required tolerance level, as the 'C' suffix denotes ±2% accuracy compared to standard variants. Confirm that the tape-and-reel packaging aligns with automated assembly requirements. Ensure the component meets material categorization compliance standards relevant to your manufacturing region before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when precise voltage regulation is critical due to its tighter tolerance band. The DO-35 package is suitable for applications requiring robust mechanical stability and high thermal endurance. Evaluate the dynamic resistance and temperature coefficient against circuit sensitivity requirements to ensure stable performance across varying load and environmental 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 Zener voltage range from 2.4 V to 75 V. Variants are available in multiple packages including MiniMELF, SOT-23, and SOD-123, allowing designers flexibility in board space and thermal management strategies while maintaining consistent electrical characteristics.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering DO-35 packaged Zener diodes rated at 68 V with ±2% tolerance. Verify that replacement parts match the 500 mW power dissipation limit and the 175 °C maximum junction temperature rating to maintain circuit reliability and thermal safety margins.
