1N5226BTR

Single Zener Diodes Overview

The onsemi 1N5226BTR is a single-channel Zener diode with a nominal voltage of 3.3 V and a maximum power dissipation of 500 mW. It utilizes the DO-35 axial lead package for through-hole mounting. The device features a 5% voltage tolerance, a test current of 20 mA, and a maximum Zener impedance of 28 Ω at the test current. Maximum reverse leakage current is specified at 25 µA. Operating junction temperature ranges from -65 °C to +200 °C, with storage temperatures spanning the same range.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation within a tight 5% tolerance band
• Engineered for high thermal stability across extreme operating environments
• Constructed in a hermetically sealed glass axial lead package

Single Zener Diodes Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection stages in electronic systems
• General-purpose voltage regulation tasks

Single Zener Diodes Procurement Notes

Verify that the ordering suffix TR corresponds to tape and reel packaging containing 5000 units per reel. Confirm the component matches the specific 1N5226B electrical characteristics outlined in the official datasheet. Ensure the supplier provides traceability documentation consistent with onsemi manufacturing standards.

Single Zener Diodes Selection Notes

Select this component when a 3.3 V reference point is required with strict tolerance limits. Evaluate the 500 mW power dissipation capability against expected circuit loads. Consider the DO-35 package dimensions for physical layout constraints and verify compatibility with automated assembly processes utilizing tape and reel formats.

Single Zener Diodes Part Context

This part belongs to the 1N5221B through 1N5252B series of silicon planar Zener diodes manufactured by onsemi. The series covers a wide voltage range from 2.28 V to 24.0 V. All devices share common mechanical specifications, including the DO-35 glass case and Pb-free/halide-free construction.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering standard 1N5226B equivalents. Verify that substitute parts meet the identical 3.3 V nominal voltage, 5% tolerance, and 500 mW power rating requirements.
