1N5266C-TAP

Single Zener Diodes Overview

The Vishay 1N5266C-TAP is a silicon planar power Zener diode in the DO-35 (DO-204AH) axial leaded package. It provides 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. Key electrical parameters include a maximum reverse leakage current of 0.1 µA at 25 V, a typical dynamic resistance of 230 Ω, 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 stability across an extended junction temperature range from -65 °C to +175 °C
• Standardized axial leaded construction for reliable through-hole mounting

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify that the ordering code includes the 'C' suffix to ensure the required ±2 % tolerance specification is met. Confirm the '-TAP' designation corresponds to the specific ammopack tape configuration required for your assembly line equipment. Cross-reference the document revision date against your internal quality standards to ensure compliance with the latest manufacturing specifications.

Single Zener Diodes Selection Notes

Select this component when circuit design requires a stable 68 V reference with strict tolerance limits. The DO-35 package is suitable for applications where standard through-hole technology is mandated. Evaluate the 230 Ω dynamic resistance to ensure it meets the ripple rejection requirements of your specific load 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 voltage range from 2.4 V to 75 V. The 'C' variant specifically denotes tighter manufacturing tolerances compared to the standard 'B' version, making it suitable for high-precision analog and digital control applications.

Single Zener Diodes Replacement Considerations

Compatible substitutes within the same Vishay family include the 1N5266B-TAP, which offers a wider ±5 % tolerance. Other manufacturers producing equivalent 68 V Zener diodes in the DO-35 package may be considered if their datasheets confirm matching electrical characteristics and thermal ratings.
