1N5228B-T

Single Zener Diodes Overview

The Vishay 1N5228B-T is a silicon planar power Zener diode with a nominal voltage of 3.9 V and a ±5% tolerance. It operates in the DO-35 (DO-204AH) axial leaded package, providing a maximum power dissipation of 500 mW at thermal equilibrium. The device features a test current of 20 mA, a maximum reverse leakage current of 10 µA at 1 V, and a dynamic resistance of 23 Ω. It supports a junction temperature range up to 175 °C and a storage temperature range from -65 °C to +175 °C.

Single Zener Diodes Feature Summary

• Utilizes silicon planar technology for robust voltage regulation
• Features hermetically sealed glass construction in an axial leaded package
• Provides standard ±5% Zener voltage tolerance for general applications

Single Zener Diodes Applications

• Voltage stabilization circuits
• General-purpose voltage reference applications
• Low-power electronic protection designs

Single Zener Diodes Procurement Notes

Verify that the ordering code explicitly includes the suffix '-TAP' to confirm the specific taped-and-reeled packaging format. Ensure the component matches the required ±5% tolerance designation ('B') and the DO-35 package style. Confirm compliance with material categorization standards as defined by the manufacturer before finalizing procurement specifications.

Single Zener Diodes Selection Notes

Select this component when a stable 3.9 V reference is needed within a low-power constraint. The DO-35 package allows for through-hole mounting, suitable for standard PCB layouts. Consider the negative temperature coefficient typical for voltages below 5 V when designing for wide thermal operating ranges.

Single Zener Diodes Part Context

This part belongs to the Vishay 1N5221 to 1N5267 series of small signal Zener diodes. The series covers a broad voltage range from 2.4 V to 75 V, offering various tolerance options including tighter ±2% variants designated with a 'C' suffix. These diodes are widely used across industrial and consumer electronics for basic voltage regulation tasks.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers' 1N5228 equivalents. Verify that substitute parts match the 3.9 V nominal voltage, 500 mW power rating, and DO-35 package dimensions to ensure mechanical and electrical compatibility.
