PZU11B1,115

Single Zener Diodes Overview

The Nexperia PZU11B1,115 is a Zener voltage regulator diode housed in the SOD323 (SC-76) surface-mounted plastic package. It features a nominal Zener voltage of 11 V with a tight tolerance series B1 specification of approximately ±2%. The device supports a total power dissipation of up to 320 mW and operates within a wide working voltage range from 2.4 V to 51 V. Designed for general regulation functions, it offers low reverse current characteristics suitable for compact circuit designs.

Single Zener Diodes Feature Summary

• Tight voltage tolerance of approximately ±2% provided by the B1 series classification
• Compact SOD323 surface-mount package optimized for high-density PCB layouts
• Low reverse leakage current ensuring minimal power loss in standby states

Single Zener Diodes Applications

• General voltage regulation circuits
• Voltage reference applications requiring stable bias levels
• Overvoltage protection stages in signal lines

Single Zener Diodes Procurement Notes

Verify the specific suffix '115' corresponds to the standard tape-and-reel packaging format required for automated assembly processes. Confirm that the B1 tolerance variant meets the strict voltage accuracy requirements of the target design, as other tolerance options exist within the same product family.

Single Zener Diodes Selection Notes

Select this component when a precise ±2% Zener voltage is necessary in a minimal footprint. The SOD323 package allows for space-constrained designs while maintaining adequate thermal performance for general-purpose regulation tasks. Ensure the operating current remains within limits to sustain the specified breakdown characteristics.

Single Zener Diodes Part Context

This part belongs to the Nexperia PZU series of general-purpose Zener diodes. The series provides various voltage options and tolerance grades, including B (±5%), B1/B2/B3 (±2%), and specialized variants. The PZU11B1 specifically targets applications demanding higher precision than standard ±5% devices without requiring larger packages.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other manufacturers' 11 V Zener diodes in the SOD323 package with ±2% tolerance. Verify equivalent power dissipation ratings and thermal resistance values to ensure reliable operation under identical load conditions.
