1N4702UR-1/TR

Overview

The 1N4702UR-1/TR is a surface-mount Zener diode manufactured by Microchip Technology. It features a nominal Zener voltage of 15 V with a tolerance of ±5%. The device is designed for a power dissipation of 500 mW and utilizes the DO-213AA-2 package. It operates as a unidirectional voltage regulator diode constructed from silicon.

Feature Summary

• Hermetically sealed glass construction for environmental protection
• Surface mount design in compact DO-213AA-2 package
• Silicon oxide passivated junction technology

Applications

• Voltage regulation circuits
• Overvoltage protection
• Reference voltage generation

Procurement Notes

Verify component authenticity through authorized Microchip distributors or direct channels. Confirm RoHS compliance status, as sources indicate this specific part may not be compliant. Check current availability as some listings suggest discontinuation or limited stock. Ensure the DO-213AA-2 package matches your PCB footprint requirements before ordering.

Selection Notes

Select this component when a hermetically sealed, surface-mount Zener diode is required for 15 V regulation. The DO-213AA-2 package suits space-constrained designs. Verify thermal management capabilities for 500 mW dissipation. Consider leaded alternatives if surface mount assembly is not feasible or if non-hermetic packages are acceptable.

Part Context

This part belongs to the 1N4702 series of Zener diodes. It shares specifications with the 1N4702RR1 but differs in packaging, utilizing the SMT DO-213AA-2 format instead of the axial DO-35. It serves as a ruggedized voltage reference solution within Microchip's discrete semiconductor portfolio.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Users should consult Microchip technical support for qualified replacements or equivalent components from other manufacturers that match the 15 V, 500 mW, and DO-213AA-2 specifications.
