• Biasing networks in analog signal processing

Single Zener Diodes Procurement Notes

Verify the specific ordering code PZU9.1B2,115 against official Nexperia documentation to ensure correct tolerance and package variant. Confirm compliance requirements such as RoHS 3 and REACH status prior to integration. Cross-reference datasheet parameters including Zener impedance and leakage current to validate suitability for the target application environment.

Single Zener Diodes Selection Notes

Select this component when a stable 9.1 V reference with high accuracy is required in a small form factor. The ±2% tolerance distinguishes it from standard 5% variants, making it suitable for precision applications. Ensure the SOD-323 footprint matches the PCB layout and that the 320 mW power rating accommodates the expected thermal load in the final assembly.

Single Zener Diodes Part Context

This part belongs to the PZU3.0 series of single Zener diodes from Nexperia, optimized for general-purpose voltage regulation in consumer electronics and industrial equipment. The PZU9.1B2 variant specifically targets applications requiring higher voltage references compared to lower-voltage siblings like the PZU3.0B2. It shares the same SOD-323 package family, ensuring design consistency across different voltage levels.
