1N5229/TR

Single Zener Diodes Overview

The Microchip Technology 1N5229/TR is a Zener diode designed for voltage regulation applications. It operates within a temperature range of -65°C to +175°C TJ and features a maximum power dissipation of 500 mW. The device utilizes a DO-35 (DO-204AH) axial through-hole package, suitable for automated assembly via reel packaging. Key electrical characteristics include a nominal Zener voltage of 4.3 V with a tolerance of 5%, a test current of 5 mA, and a maximum reverse leakage current of 1 µA at the rated voltage. The forward voltage drop is specified at 1.1 V under a forward current of 200 mA.

Single Zener Diodes Feature Summary

Single Zener Diodes Procurement Notes

Verify the specific suffix and package variant against the official Microchip datasheet to ensure compatibility with design requirements. Confirm RoHS compliance status and environmental declarations prior to integration. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability. Ensure storage conditions align with semiconductor handling standards to prevent degradation.

Single Zener Diodes Selection Notes

Select this component when a 4.3 V regulation point is required with low leakage characteristics. Evaluate the thermal management needs based on the 500 mW power dissipation limit. Consider the axial lead form factor for PCB layout constraints. Compare alternative Zener voltages if the system requires different reference levels or tighter tolerance bands.

Single Zener Diodes Part Context

This component belongs to the standard 1N52xx series of Zener diodes manufactured by Microchip Technology. The series offers a wide range of voltage options from low-voltage references to higher voltage regulators. The '/TR' suffix indicates tape and reel packaging, facilitating high-volume automated placement processes in manufacturing environments.

Single Zener Diodes Replacement Considerations

Direct replacements must match the 4.3 V Zener voltage, 500 mW power rating, and DO-35 package. Verify that substitute parts meet the same leakage current and temperature specifications. Check for pinout compatibility and mechanical dimensions to ensure seamless integration into existing footprints.
