• Silicon oxide passivated junction technology

Single Zener Diodes Applications

• Voltage regulation circuits
• Overvoltage protection
• Reference voltage generation

Single Zener Diodes 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.

Single Zener Diodes 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.

Single Zener Diodes 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.

Single Zener Diodes 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.
