1N5234BUR-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N5234BUR-1/TR is a surface mount Zener voltage regulator with a nominal breakdown voltage of 6.2 V at a test current of 20 mA. It operates within a junction temperature range of -65°C to +175°C and dissipates up to 0.5 W. The device features a maximum dynamic impedance of 7 Ohms, a reverse leakage current of 5 µA, and a positive temperature coefficient of +0.045 %/°C. Packaged in the hermetically sealed DO-213AA (MELF) configuration, it utilizes an internal metallurgical bond for reliability.

Single Zener Diodes Feature Summary

• Hermetically sealed glass DO-213AA package with internal metallurgical bonding
• Surface mount equivalent to JEDEC registered axial-leaded series
• Inherently radiation hard design
• Non-sensitive to electrostatic discharge

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges
• High-reliability electronic circuits requiring radiation hardness
• ESD-sensitive environment protection

Single Zener Diodes Procurement Notes

Verify that the ordering suffix TR indicates tape and reel packaging per EIA-481-B standards. Confirm the B suffix corresponds to the required 5% voltage tolerance. Ensure compatibility with the specified DO-213AA footprint and soldering parameters before procurement.

Single Zener Diodes Selection Notes

Select this component when a ruggedized surface mount solution is required instead of traditional axial leads. The 6.2 V rating suits mid-range reference applications. Verify thermal management requirements against the 250 °C/W junction-to-ambient resistance for FR4 mounting conditions.

Single Zener Diodes Part Context

This part belongs to the 1N5221BUR-1 through 1N5281BUR-1 series, providing a metallurgically bonded surface mount alternative to standard JEDEC registered diodes. The series covers voltages from 2.4 V to 200 V, offering various tolerance options including 1%, 2%, 5%, and 10%.

Single Zener Diodes Replacement Considerations

Direct replacements include other manufacturers' DO-213AA Zener diodes with identical 6.2 V ratings and 500 mW power dissipation. Verify pinout polarity and thermal characteristics match the original design constraints.
