1N5523A/TR

Overview

The Microchip Technology 1N5523A/TR is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 5.1 V with a tolerance of ±5%. The device operates within a power dissipation limit of 500 mW and maintains a maximum reverse leakage current of 2 µA at the specified test conditions. Electrical characterization includes a Zener impedance of 26 Ohms measured at a test current of 5 mA. The component supports an operating temperature range from -65 °C to +175 °C junction temperature. It utilizes the DO-213AA-2 package, also known as SOD-80, suitable for surface mount technology. The unit weight is recorded as 40 mg.

Feature Summary

• Provides stable voltage reference capabilities through precise Zener breakdown characteristics.
• Supports high-temperature operation up to 175 °C junction temperature for demanding environments.
• Utilizes a compact surface mount package design for automated assembly integration.

Applications

• Voltage regulation in electronic circuits
• Reference voltage generation for analog systems
• Overvoltage protection stages

Procurement Notes

Verify the specific suffix designation against official Microchip documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with surface mount assembly processes given the DO-213AA-2 form factor. Cross-reference electrical parameters such as Zener impedance and leakage current with the latest datasheet revisions prior to final procurement decisions.

Selection Notes

Select this component when a 5.1 V reference is required in a surface mount configuration. Evaluate the 500 mW power rating against expected thermal loads in the target application. Confirm that the ±5% voltage tolerance meets circuit precision requirements. Verify that the operating temperature range aligns with the environmental conditions of the end-use system.

Part Context

This part belongs to the standard Zener diode family manufactured by Microchip Technology. It shares common electrical characteristics with other variants in the series but differs in packaging and specific tolerance grades. The TR suffix indicates reel packaging for high-volume surface mount production lines.

Replacement Considerations

Consult official substitution guides for parameter-equivalent alternatives. Verify pinout compatibility and thermal performance before replacing with generic equivalents.
