1N5224B-TR

Single Zener Diodes Overview

The Vishay 1N5224B-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 provides a nominal Zener voltage of 2.8 V with a standard ±5% tolerance. 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 Ω and a typical negative temperature coefficient of -0.08 %/K.

Single Zener Diodes Procurement Notes

Verify that the ordering code includes the specific suffixes required for your packaging needs. Confirm the exact part number matches the datasheet specifications before finalizing orders. Ensure compliance with material categorization definitions provided by the manufacturer. Validate all operating parameters against your specific application requirements prior to implementation.

Single Zener Diodes Selection Notes

Select this component when a precise 2.8 V reference is needed in an axial through-hole configuration. Consider the negative temperature coefficient for thermal stability analysis. Evaluate the 500 mW power dissipation limit relative to ambient conditions. Compare dynamic impedance values against circuit sensitivity requirements.

Single Zener Diodes Part Context

This device belongs to the extensive 1N5221 to 1N5267 family of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide range of voltages from 2.4 V to 75 V. The 'B' suffix denotes the standard ±5% voltage tolerance variant available in taped and reel or ammopack formats.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering equivalent 2.8 V Zener diodes in the DO-35 package. Verify matching electrical parameters such as dynamic resistance and power dissipation. Ensure physical dimensions are compatible with existing board layouts.
