1N5252BUR-1

Single Zener Diodes Overview

The 1N5252BUR-1 is a single Zener voltage regulator manufactured by Microchip Technology, designed for surface mount applications. It features a DO-213AA-2 package and provides a nominal Zener voltage of 24 V with a 5% tolerance. The device dissipates up to 500 mW and operates within a temperature range of -65°C to +175°C. Key electrical parameters include a maximum reverse leakage current of 100 nA, a Zener impedance of 33 Ohms at a test current of 5.2 mA, and a forward voltage of 1.1 V.

Single Zener Diodes Feature Summary

• Metallurgically bonded glass surface mount construction
• Hermetically sealed package design
• Surface mount equivalent to JEDEC registered 1N5221 series

Single Zener Diodes Applications

• Voltage regulation in surface mount circuits
• Reference voltage sources
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify the specific suffix and revision level against the manufacturer's latest datasheet to ensure compatibility with your design requirements. Confirm RoHS status and compliance details directly with Microchip Technology or authorized distributors prior to ordering, as manufacturing specifications may be subject to change without notice.

Single Zener Diodes Selection Notes

Select this component when a 24 V reference is required in a compact surface mount form factor. Ensure the circuit design accommodates the 500 mW power dissipation limit and the specified operating temperature range. Verify that the 33 Ohm Zener impedance meets the dynamic performance needs of the application.

Single Zener Diodes Part Context

This part belongs to the 1N5221BUR-1 through 1N5281BUR-1 series, which offers surface mount equivalents to the traditional through-hole 1N5221 to 1N5281 Zener diodes. The series utilizes a metallurgically bonded configuration to provide robust performance in space-constrained electronic designs requiring reliable voltage regulation.

Single Zener Diodes Replacement Considerations

Direct substitutes include other 1N5252 variants from Microchip such as the non-BUR-1 version for through-hole mounting, provided the package difference is acceptable. Cross-brand replacements must match the 24 V Zener voltage, 500 mW power rating, and DO-213AA footprint.
