1N5233BUR-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N5233BUR-1/TR is a surface mount Zener voltage regulator with a nominal breakdown voltage of 6.0 V and a maximum power dissipation of 0.5 W. It features a metallurgically bonded glass DO-213AA package, offering hermetic sealing for reliability. The device provides a tight voltage tolerance of ±5% (indicated by the 'B' suffix) and operates within a junction temperature range of -65°C to +175°C. Electrical characteristics include a test current of 20 mA, a maximum dynamic impedance of 7.0 Ohms at IZT, and a maximum reverse leakage current of 5.0 µA.

Single Zener Diodes Feature Summary

• Hermetically sealed metallurgically bonded glass construction in a surface mount DO-213AA package.
• Provides stable voltage regulation across a broad operating current and temperature range.
• Inherently radiation hard per Microsemi specifications.
• Non-sensitive to electrostatic discharge events.

Single Zener Diodes Applications

• Voltage regulation in harsh environments requiring radiation hardness.
• Precision reference circuits utilizing tight voltage tolerances.
• Surface mount designs replacing axial-leaded equivalents.

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's nomenclature guide to confirm RoHS compliance status and tolerance class. Ensure the procurement documentation explicitly references the MIL-PRF-19500 screening level if required for mission-critical applications. Confirm that the tape and reel packaging matches standard EIA-481-B specifications for automated assembly integration.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed surface mount solution is required for high-reliability applications. The 1N5233BUR-1 offers a 6.0 V regulation point with ±5% accuracy. Consider the thermal resistance values and derating curves for PCB layout planning. Verify compatibility with existing JEDEC registered circuit designs transitioning to surface mount technology.

Single Zener Diodes Part Context

This part belongs to the 1N5221BUR-1 through 1N5281BUR-1 series, which serves as the surface mount equivalent to the popular JEDEC registered 1N5221 to 1N5281 axial series. The series covers Zener voltages from 2.4 to 200 volts. The 'BUR-1' designation indicates a metallurgically bonded package with specific tolerance levels, while the 'TR' suffix denotes tape and reel packaging.

Single Zener Diodes Replacement Considerations

The 1N5233B is a parameter-equivalent axial-leaded alternative within the same family. Both devices share identical electrical characteristics but differ in package style and mounting method. Verify footprint compatibility and thermal management requirements when substituting between surface mount and through-hole variants.
