1N4624UR-1

Single Zener Diodes Overview

The Microchip Technology 1N4624UR-1 is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 4.7 V with a tolerance of ±5%. The device operates in the SMD/SMT configuration within a DO-213AA-2 package, supporting through-hole or surface-mount installation styles depending on specific variant interpretations, though officially listed as SMD/SMT here. Key electrical parameters include a maximum power dissipation of 500 mW and a maximum reverse leakage current of 5 µA at specified conditions. The unit weight is recorded as 40 mg.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation with a nominal 4.7 V Zener breakdown.
• Engineered for surface-mount technology (SMD/SMT) integration.
• Constructed in a compact DO-213AA-2 package format.

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify the exact datasheet revision and RoHS compliance status directly with Microchip Technology before procurement, as environmental declarations may vary by production batch. Confirm that the DO-213AA-2 package dimensions align with your PCB footprint requirements. Ensure that the 500 mW power rating is sufficient for your specific thermal management design to prevent overheating during operation.

Single Zener Diodes Selection Notes

Select this component when a 4.7 V regulation point is required in a surface-mount form factor. Compare the 5 µA leakage current against circuit sensitivity requirements. Evaluate the DO-213AA-2 package size against available board space constraints relative to other Zener diode options in the same voltage class.

Single Zener Diodes Part Context

This part belongs to the Microchip Technology discrete semiconductor portfolio, specifically within the Zener diodes subcategory. It serves as a surface-mount alternative to axial leaded variants like the 1N4624 series, maintaining similar electrical characteristics while adapting to modern automated assembly processes.

Single Zener Diodes Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Consult Microchip Technology for qualified equivalents or cross-reference compatible SMD Zener diodes with identical 4.7 V ratings and DO-213AA-2 packaging.
