1N5222B-TAP

Single Zener Diodes Overview

The Vishay 1N5222B-TAP is a silicon planar power Zener diode housed in a DO-35 (DO-204AH) axial glass package. It provides a nominal Zener voltage of 2.5 V with a standard tolerance of ±5%, indicated by the 'B' suffix. The device operates at a test current of 20 mA and supports a maximum power dissipation of 500 mW. Key electrical characteristics include a dynamic resistance of 30 Ω, a reverse leakage current of 100 µA at 1 V, and a forward voltage of 1.1 V at 200 mA. The component features a junction temperature rating of 175 °C and a storage range from -65 °C to +175 °C.

Single Zener Diodes Procurement Notes

Verify that the ordering code matches the required tolerance level, as the 'B' suffix specifically denotes ±5% Zener voltage tolerance. Confirm the package type is DO-35 (DO-204AH) and ensure the supplier documentation aligns with Vishay's official specifications. Check material categorization compliance if specific environmental standards are required for your application.

Single Zener Diodes Selection Notes

Select this component when a precise 2.5 V reference is needed within a ±5% margin. Ensure the circuit design accommodates the 500 mW power dissipation limit and the thermal resistance characteristics provided in the datasheet. Consider the axial lead configuration for through-hole mounting requirements and verify that the operating temperature range meets the system's environmental conditions.

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 Zener voltage range from 2.4 V to 75 V. The 'B' suffix indicates the standard ±5% tolerance variant, while 'C' variants offer tighter ±2% tolerance. These diodes are designed for general-purpose voltage regulation tasks in electronic circuits.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering 1N5222 equivalents in the DO-35 package. Verify that substitute parts meet the same 2.5 V nominal voltage, 500 mW power rating, and ±5% tolerance specifications to ensure functional compatibility.

Single Zener Diodes FAQ
