1N5226B-T

Single Zener Diodes Overview

The Diodes Incorporated 1N5226B-T is a 500mW epitaxial Zener diode housed in a DO-35 glass axial package. It provides a nominal Zener voltage of 3.3V with a ±5% tolerance, tested at 20mA. The device features a maximum dynamic impedance of 28Ω and a reverse leakage current of 25µA at 1.0V. It operates within a temperature range of -65°C to +200°C and includes a tin-silver lead finish compliant with RoHS standards.

Single Zener Diodes Feature Summary

• Epitaxial construction for high stability
• Glass passivated junction in DO-35 case
• Lead-free finish compatible with RoHS directives

Single Zener Diodes Applications

• Voltage regulation circuits
• Reference voltage generation
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify the specific suffix '-T' corresponds to tape and reel packaging containing 5,000 units per reel. Confirm that the component meets RoHS3 requirements and check for any applicable EU directive exemptions regarding glass or soldering materials. Ensure the ordering code matches the required mechanical dimensions and terminal finish specifications.

Single Zener Diodes Selection Notes

Select this component when a 3.3V reference with tight tolerance is required in an axial through-hole format. Consider the thermal resistance and power derating curves if operating near the maximum junction temperature limit. Verify compatibility with existing PCB footprints designed for the DO-35 package geometry.

Single Zener Diodes Part Context

This part belongs to the 1N5221B through 1N5267B series of silicon planar Zener diodes manufactured by Diodes Incorporated. The series covers a wide voltage range from 2.4V to 75V, utilizing a consistent DO-35 glass package structure across all variants for standardized mounting and handling.

Single Zener Diodes Replacement Considerations

Diodes Incorporated recommends using the MMSZ52xxB surface mount equivalents for new designs. Cross-reference with other manufacturers offering 1N5226B variants in DO-35 packages, ensuring electrical parameters such as impedance and leakage current remain within acceptable limits.
