1N5226B-T

Single Zener Diodes Overview

The Vishay General Semiconductor - Diodes Division 1N5226B-T is a silicon planar epitaxial Zener diode housed in a DO-35 glass axial leaded package. It provides a nominal Zener voltage of 3.3 V with a ±5% tolerance at a test current of 20 mA. The device dissipates up to 500 mW and features a maximum dynamic impedance of 28 Ω. It operates within a temperature range of -65°C to +200°C, includes a cathode band for polarity identification, and utilizes a Sn96.5Ag3.5 terminal finish compliant with RoHS directives.

Single Zener Diodes Feature Summary

• Epitaxial silicon planar construction for high stability
• Hermetic glass passivated junction in a DO-35 case
• Lead-free finish compatible with standard soldering processes

Single Zener Diodes Applications

• Voltage regulation in electronic circuits
• Voltage reference applications
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify the specific manufacturer source, as the datasheet originates from Diodes Incorporated while the requested brand is Vishay. Confirm that the -T suffix corresponds to tape and reel packaging if required. Ensure compliance with the stated RoHS exemptions for glass and high-temperature soldering applies to your manufacturing process.

Single Zener Diodes Selection Notes

Select this component when a 3.3 V reference with ±5% tolerance is needed in an axial through-hole configuration. Consider the -65°C to +200°C operating range for wide environmental applications. Note that the datasheet indicates surface mount equivalents are available for designs requiring different form factors.

Single Zener Diodes Part Context

This part belongs to the 1N5221B through 1N5267B series of 500mW epitaxial Zener diodes. The series covers a broad voltage range from 2.4 V to 75 V. The 'B' suffix denotes the standard ±5% voltage tolerance. The DO-35 package is a standard JEDEC outline for small-signal glass-passivated diodes.

Single Zener Diodes Replacement Considerations

The datasheet explicitly recommends using MMSZ52xxB devices instead of this part for new designs. Verify pinout compatibility and thermal resistance characteristics when substituting with other manufacturers' DO-35 Zener diodes.
