1N5226C-TR

Single Zener Diodes Overview

The Vishay 1N5226C-TR is a silicon planar power Zener diode in the DO-35 (DO-204AH) axial leaded package. It provides a nominal Zener voltage of 3.3 V with a tight ±2 % tolerance, indicated by the 'C' suffix. The device operates at a test current of 20 mA and dissipates up to 500 mW. Key electrical parameters include a maximum dynamic resistance of 28 Ω, a reverse leakage current of 25 μA at 1 V, and a typical temperature coefficient of -0.07 %/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 junction temperature of 175 °C
• Low forward voltage drop characteristic for efficient circuit integration

Single Zener Diodes Applications

• Voltage stabilization circuits
• Reference voltage generation
• Overvoltage protection

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 specifications for automated assembly processes.

Single Zener Diodes Selection Notes

Select this component when precise voltage reference stability is critical. The tighter tolerance requires careful consideration of the negative temperature coefficient inherent to low-voltage Zener diodes during thermal design.

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 range of nominal voltages from 2.4 V to 75 V, utilizing a standardized DO-35 glass passivated junction construction.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering 3.3 V Zener diodes in the DO-35 package. Verify that replacement parts meet or exceed the 500 mW power dissipation rating and maintain equivalent ±2 % tolerance specifications.
