1N5222C-TR

Single Zener Diodes Overview

The Vishay 1N5222C-TR is a silicon planar power Zener diode with a nominal voltage of 2.5 V and a maximum power dissipation of 500 mW. It features a tight voltage tolerance of ±2% and operates within a junction temperature range of -65 °C to +175 °C. The device utilizes a DO-35 (DO-204AH) axial through-hole package, weighs approximately 125 mg, and has a UL 94 V-0 flammability rating. It is supplied in reels of 10,000 units.

Single Zener Diodes Feature Summary

• High precision voltage regulation with a ±2% tolerance for stable reference applications
• Robust thermal performance supporting operation up to a 175 °C junction temperature
• Standardized DO-35 axial leaded package suitable for automated through-hole assembly

Single Zener Diodes Applications

• Voltage stabilization circuits
• Precision voltage references
• Overvoltage protection stages

Single Zener Diodes Procurement Notes

Verify the specific suffix 'C' confirms the required ±2% tolerance level against your design specifications. Ensure the reel quantity aligns with production volume requirements. Confirm that the DO-35 package dimensions fit the target PCB footprint. Validate compliance with material categorization standards if applicable to your manufacturing process.

Single Zener Diodes Selection Notes

Select this component when a precise 2.5 V reference is needed with tighter tolerances than standard variants. Consider the 500 mW power rating for thermal management in enclosed environments. Evaluate the axial lead length for mechanical stability during wave soldering processes compared to surface mount alternatives.

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' suffix specifically denotes the tighter ±2% tolerance band, distinguishing it from the standard ±5% 'B' suffix devices within the same product family.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering DO-35 packaged Zener diodes rated at 2.5 V with ±2% tolerance. Verify that equivalent parts match the 500 mW power dissipation and 175 °C maximum junction temperature limits.
