1N5223B-TR

Single Zener Diodes Overview

The Vishay 1N5223B-TR is a silicon planar power Zener diode with a nominal voltage of 2.7 V and a maximum power dissipation of 500 mW. It features a standard tolerance of ±5% (indicated by the 'B' suffix) and operates within a temperature range of -65°C to +175°C. The device utilizes a DO-35 axial through-hole package, weighs approximately 125 mg, and has a UL 94 V-0 flammability rating. Electrical characteristics include a test current of 20 mA, a maximum reverse leakage current of 75 µA at 1 V, and a dynamic resistance of 30 Ω.

Single Zener Diodes Procurement Notes

Verify that the ordering code includes the '-TR' suffix to confirm taped-and-reeled packaging. Ensure the required tolerance matches the 'B' designation for ±5%. Confirm compliance with RoHS3 standards and check material categorization documentation for specific supply chain requirements before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a 2.7 V reference with moderate precision is required in a through-hole configuration. Consider the thermal resistance and lead length constraints for power dissipation calculations. Evaluate the dynamic resistance and leakage current specifications against circuit sensitivity requirements to ensure adequate signal integrity.

Single Zener Diodes Part Context

This part belongs to the 1N5221 to 1N5267 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide voltage range from 2.4 V to 75 V, offering various tolerance options including ±5% ('B') and ±2% ('C'). These diodes are designed for general-purpose voltage regulation applications in consumer and industrial electronics.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same Vishay series include other 1N52xxB variants with different voltage ratings. Cross-manufacturer equivalents must match the 2.7 V nominal voltage, 500 mW power rating, and DO-35 package dimensions. Verify electrical parameters such as dynamic resistance and leakage current to ensure functional compatibility.
