1N5253

Single Zener Diodes Overview

The Microchip Technology 1N5253 is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 25 V with a 5% tolerance and operates within a power dissipation rating of 500 mW. The device utilizes a DO-35 glass axial-lead package, suitable for through-hole mounting. Electrical characteristics include a maximum reverse leakage current of 100 nA, a Zener impedance of 44 Ohms, and a test current of 4.5 mA. It maintains functionality across an extended temperature range from -65°C to +200°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation using a 25 V Zener breakdown characteristic in a standard DO-35 glass axial-lead package.

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection
• General-purpose voltage regulation

Single Zener Diodes Procurement Notes

Verify the specific suffix letter (e.g., 'B' or 'A') against the datasheet to confirm voltage tolerance accuracy, as this affects performance specifications. Ensure the procurement order matches the required package style and thermal operating limits defined in the official component documentation.

Single Zener Diodes Selection Notes

Select this component when a 25 V regulation point is required with moderate precision. Consider the 500 mW power dissipation limit and the wide operating temperature range for suitability in harsh environments. Verify that the DO-35 package dimensions align with the target PCB layout constraints.

Single Zener Diodes Part Context

This part belongs to the 1N5221 through 1N5281 series of 0.5 W Zener Voltage Regulators. The series offers a broad selection of voltages from 2.4 V to 200 V in standard tolerances. These components are widely used in general electronic designs requiring reliable voltage clamping or referencing.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering 1N5253 equivalents in the DO-35 package. Verify that substitute parts meet the same 25 V nominal voltage, 500 mW power rating, and electrical parameters specified by Microchip Technology.
