1N4703UR-1

Overview

The Microchip Technology 1N4703UR-1 is a single Zener diode designed for surface mount applications. It features a nominal Zener voltage of 16 V with a tolerance of ±5%. The device has a power dissipation rating of 500 mW and utilizes the DO-213AA (SOD-80) package. It is classified as a silicon unidirectional component suitable for voltage regulation tasks.

Feature Summary

• Provides stable voltage regulation at a nominal 16 V level
• Designed for surface mount technology integration
• Utilizes hermetically sealed glass MELF construction

Applications

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

Procurement Notes

Verify the specific suffix UR-1 against the manufacturer's current datasheet to confirm package type and compliance status. Ensure the procurement channel provides official documentation for the DO-213AA variant. Cross-reference the part number with Microchip Technology records to validate authenticity and technical specifications before purchase.

Selection Notes

Select this component when a 16 V Zener voltage is required in a compact surface mount form factor. The 500 mW power rating suits low-current regulation applications. Confirm that the DO-213AA footprint matches the PCB design constraints and that the ±5% tolerance meets the circuit's precision requirements.

Part Context

This part belongs to the Microchip Technology series of single Zener diodes. It is manufactured under the Microsemi brand lineage, now integrated into Microchip. The 1N4703 designation typically corresponds to a 16 V specification within this standardized product family.

Replacement Considerations

Compatible substitutes include the 1N4703A from other manufacturers offering identical 16 V, 500 mW specifications in SOD-80 packages. Verify pinout compatibility and thermal characteristics when substituting.
