1N5222C-TAP

Single Zener Diodes Overview

The Vishay 1N5222C-TAP is a silicon planar power Zener diode in the DO-35 (DO-204AH) axial leaded package. It provides a nominal Zener voltage of 2.5 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 of power. Key electrical characteristics include a maximum dynamic resistance of 30 Ohms and a reverse leakage current of 100 µA at 1 V. It supports junction temperatures up to 175 °C.

Single Zener Diodes Feature Summary

• High precision voltage regulation with ±2% tolerance
• Robust thermal performance for continuous operation
• Standardized axial leaded packaging for through-hole mounting

Single Zener Diodes Applications

• Voltage stabilization circuits
• Precision reference voltage generation
• Over-voltage protection stages

Single Zener Diodes Procurement Notes

Verify that the specific ordering code includes the TAP suffix to ensure receipt in ammopack tape format rather than reel packaging. Confirm the C-suffix designation matches the required ±2% tolerance specification for your circuit design. Cross-reference the document revision date to ensure compliance with the latest Vishay material categorization and environmental standards.

Single Zener Diodes Selection Notes

Select this component when precise low-voltage regulation is critical, as the C-suffix guarantees tighter tolerances than standard B-suffix variants. Ensure the application current does not exceed the 20 mA test current threshold to maintain accuracy. Verify that the DO-35 package dimensions fit the target PCB layout and that the 500 mW power dissipation rating accommodates the expected thermal load.

Single Zener Diodes Part Context

This part belongs to the 1N5221 to 1N5267 series of small signal Zener diodes manufactured by Vishay General Semiconductor - Diodes Division. The series covers a wide range of nominal voltages from 2.4 V to 75 V. The 1N5222 variant specifically targets the 2.5 V segment, offering a stable reference point for low-voltage electronic systems requiring high reliability.

Single Zener Diodes Replacement Considerations

Compatible substitutes within the same family include the 1N5222B-TAP, which offers a wider ±5% tolerance. Other Vishay packages such as MiniMELF or SOT-23 may be considered if form factor changes are acceptable.
