1N5222B-T

Single Zener Diodes Overview

The Vishay 1N5222B-T 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 standard ±5% tolerance, indicated by the 'B' suffix, and operates within a junction temperature range up to 175 °C. Packaged in a DO-35 (DO-204AH) axial glass case, it provides low reverse leakage current and stable performance for voltage stabilization applications.

Single Zener Diodes Feature Summary

• Utilizes silicon planar technology for high stability and reliability
• Features a glass DO-35 axial package suitable for through-hole mounting
• Provides low reverse leakage current and low Zener impedance

Single Zener Diodes Applications

• Voltage stabilization circuits

Single Zener Diodes Procurement Notes

Verify that the ordering code includes the '-TR' or '-TAP' suffix to confirm reel or ammopack packaging. Ensure the part number contains the 'B' designation to match the required ±5% voltage tolerance specification. Confirm compliance with RoHS directives and material categorization requirements before procurement.

Single Zener Diodes Selection Notes

Select this component when a 2.5 V reference is needed with moderate precision. The DO-35 package supports lead lengths up to 4 mm for thermal management. Verify that the application current does not exceed the limits defined by the 500 mW power dissipation rating at the expected ambient temperature.

Single Zener Diodes Part Context

This device 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. The specific model utilizes a glass encapsulation designed for robustness and consistent electrical characteristics across varying operating conditions.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' 1N5222B variants. Cross-reference with Vishay's 1N5222B-TR or 1N5222B-TAP for identical specifications. Ensure any replacement maintains the DO-35 footprint and 500 mW power rating.
