1N5232BUR-1

Single Zener Diodes Overview

The Microchip Technology 1N5232BUR-1 is a surface mount Zener diode with a nominal voltage of 5.6 V and a maximum power dissipation of 0.5 W. It features a metallurgically bonded glass DO-213AA (SOD80/MLL34) package. The device provides a 5% voltage tolerance, a maximum dynamic impedance of 11 Ohms at 20 mA test current, and a temperature coefficient of +0.038 %/°C. It operates within a junction temperature range of -65°C to +175°C.

Single Zener Diodes Feature Summary

• Hermetically sealed surface mount package with internal metallurgical bond
• Surface mount equivalent to the JEDEC registered 1N5221 through 1N5281 series
• Inherently radiation hard per Microsemi documentation

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges
• ESD protection applications
• Radiation-hardened circuit designs

Single Zener Diodes Procurement Notes

Verify that the specific part number matches the required metallurgically bonded surface mount configuration rather than the axial-leaded variant. Confirm RoHS compliance status if applicable, as commercial versions may differ from screened military equivalents. Ensure the ordering suffix aligns with the desired tolerance level and screening requirements defined in the manufacturer's nomenclature guide.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed surface mount Zener regulator is required for space-constrained or high-reliability designs. The DO-213AA package serves as a direct footprint-compatible alternative to traditional axial leads while maintaining the electrical characteristics of the standard 1N5232B series. Consider the positive temperature coefficient for thermal stability in higher voltage applications.

Single Zener Diodes Part Context

This device belongs to the 1N5221BUR-1 through 1N5281BUR-1 series, which provides surface mount equivalents to the popular JEDEC registered axial-leaded Zener diodes. The series covers a wide voltage selection from 2.4 to 200 volts, offering various tolerance options including 1%, 2%, 5%, and 10%. These components are designed for applications requiring robust voltage regulation in compact form factors.

Single Zener Diodes Replacement Considerations

The 1N5232B-1 is the axial-leaded equivalent. For surface mount replacements, verify compatibility with the DO-213AA footprint. Other manufacturers offer SOD-80 or MLL34 packages, but hermetic sealing and radiation hardness require specific sourcing.
