Overview
The Microchip Technology 1N4697UR-1 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 is rated for a power dissipation of 500 mW and operates within a temperature range of -65 °C to +175 °C. Packaged in the surface-mount DO-213AA (SMB) format, it exhibits a maximum reverse leakage current of 1 uA. This component serves as a robust solution for circuit protection and reference voltage generation in demanding electronic environments.
Feature Summary
- Provides stable voltage regulation at a nominal 10 V level
- Capable of handling 500 mW power dissipation
- Operates reliably across an extended industrial temperature range up to 175 °C
- Utilizes a compact surface-mount DO-213AA package
Applications
- Voltage reference circuits
- Overvoltage protection
- Clamping applications
Procurement Notes
Verify the specific suffix UR-1 to confirm the DO-213AA surface-mount package variant. Ensure compatibility with automated placement equipment due to the SMB form factor. Confirm RoHS compliance status if required by assembly specifications. Cross-reference datasheets from authorized distributors to validate electrical parameters against design requirements.
Selection Notes
Select this component when a 10 V regulation point is required in a surface-mount design. The 500 mW rating supports moderate current loads. Consider the ±5% tolerance for precision requirements. The high maximum operating temperature makes it suitable for harsh environments where standard commercial grade parts may fail.
Part Context
This part belongs to the 1N469x series of Zener diodes manufactured by Microchip Technology. While the base 1N4697 designation typically refers to through-hole DO-35 packages, the UR-1 suffix specifically denotes the DO-213AA surface-mount configuration. This allows designers to maintain consistent electrical characteristics while adapting to modern PCB assembly techniques.
Replacement Considerations
Direct substitutes include other manufacturers' 1N4697 variants in DO-213AA packages. Verify pinout compatibility and thermal resistance values. Ensure replacement parts meet the same 10 V nominal voltage and 500 mW power rating specifications.
