1N4697

Overview

The Microchip Technology 1N4697 is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 10 V with a tolerance of 5%. The device operates in a DO-35 axial through-hole package and dissipates up to 500 mW of power. Key electrical characteristics include a maximum reverse leakage current of 1 uA and a test current of 50 uA. It supports an operating temperature range from -65°C to +200°C.

Feature Summary

• Provides stable voltage regulation at a nominal 10 V level
• Capable of handling high thermal loads with a maximum junction temperature of 200°C
• Utilizes a glass axial DO-35 package for reliable through-hole mounting

Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection stages in electronic systems
• General-purpose voltage regulation tasks

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheets. Confirm the specific package variant, as suffixes may indicate different tolerances or packaging styles. Ensure compliance with project requirements regarding RoHS status and lead-free specifications before finalizing procurement decisions.

Selection Notes

Select this component when a 10 V regulation point is required within a standard axial form factor. Consider the 500 mW power dissipation limit relative to circuit load conditions. Evaluate the wide operating temperature range suitability for harsh environments compared to lower-rated alternatives.

Part Context

This part belongs to the standard Zener diode family manufactured by Microchip Technology. It shares common design principles with other devices in the series but is distinguished by its specific 10 V breakdown voltage and 500 mW power rating. The DO-35 package ensures compatibility with standard PCB layouts for axial components.

Replacement Considerations

Consult official substitution guides for verified equivalents. Generic replacements must match the 10 V Zener voltage, 500 mW power rating, and DO-35 package dimensions to ensure functional compatibility without redesigning the host circuit.
