1N5252

Single Zener Diodes Overview

The Microchip Technology 1N5252 is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 24 V with a test current of 5.2 mA. The device operates in a DO-204AH (DO-35) glass axial package, providing a power dissipation rating of 500 mW. Electrical characteristics include a maximum reverse leakage current of 100 nA and a Zener impedance of 33 Ohms. The unit supports an operating temperature range from -65 °C to +175 °C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation within the 1N5221 through 1N5281 series family
• Utilizes a hermetically sealed metallurgically bonded glass construction
• Offers standard voltage tolerance options including 5% and 10%

Single Zener Diodes Applications

• Voltage stabilization circuits
• Reference voltage generation
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify the specific suffix letter on the part number to confirm the exact voltage tolerance grade, as the base designation covers multiple precision levels. Confirm compliance requirements such as RoHS status, as military screening prefixes or specific suffixes may indicate non-compliant materials like leaded terminations. Ensure the package type matches the intended PCB layout, distinguishing between axial leaded DO-35 variants and surface mount equivalents.

Single Zener Diodes Selection Notes

Select this component when a 24 V reference is required in a compact axial glass package. Consider the 500 mW power dissipation limit and thermal derating at elevated temperatures above ambient. Evaluate the 33 Ohm dynamic impedance against circuit noise sensitivity requirements. Verify that the -65 °C to +175 °C operating range meets the environmental conditions of the target application.

Single Zener Diodes Part Context

This component belongs to the widely used 1N5221 through 1N5281 series of 0.5 W Zener voltage regulators. The series provides a broad selection of voltages ranging from 2.4 V to 200 V. These devices are JEDEC registered and serve as industry-standard replacements for legacy designs requiring reliable voltage clamping or regulation in small form factors.

Single Zener Diodes Replacement Considerations

Surface mount equivalents exist within the same product family, specifically the 1N5221BUR-1 through 1N5281BUR-1 series. These variants offer identical electrical performance in a DO-213AA package. Cross-reference suffix letters to ensure the replacement matches the required voltage tolerance percentage.
