PZU3.0DB2,115

Overview

The Nexperia PZU3.0DB2,115 is a dual isolated general-purpose Zener diode housed in the SOT353 (SC-88A) surface-mounted package. It features two independent diodes within a single five-lead component. The nominal Zener voltage is 3.0 V with a tolerance of ±2%. Total power dissipation is rated at 250 mW, while non-repetitive peak reverse power dissipation reaches 40 W. Key electrical characteristics include a differential resistance of 95 Ω and a reverse leakage current of 10 µA at 0.5 mA test current. The device operates within an ambient temperature range of -55 °C to +150 °C and is qualified according to AEC-Q101 standards.

Feature Summary

• Dual isolated diode configuration for space-efficient circuit design
• Halogen-free dark-green plastic package suitable for surface mounting
• AEC-Q101 qualification for automotive application reliability

Applications

• General regulation functions

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm packaging details and manufacturing origin. Ensure compatibility with standard SOT353 footprints during PCB layout. Confirm that the selected variant meets all required thermal and electrical constraints for the intended operating environment before finalizing procurement.

Selection Notes

Select this component when dual isolated Zener regulation is required in a minimal footprint. The SOT353 package supports high-density designs. Verify that the 3.0 V nominal voltage and ±2% tolerance align with circuit requirements. Consider the 250 mW total power dissipation limit and ensure adequate thermal management on the PCB to maintain junction temperatures within specified limits.

Part Context

This part belongs to the PZUxDB2 series, which offers various nominal voltages from 2.7 V to 24 V. All variants share the same SOT353 package and dual isolated architecture. The series provides consistent performance characteristics across different voltage ratings, allowing designers to choose specific breakdown voltages without changing the physical footprint or pinout configuration.

Replacement Considerations

Direct replacements must match the SOT353 package, dual isolated topology, and 3.0 V Zener voltage. Verify that alternative components meet the ±2% tolerance and 250 mW power dissipation specifications. Ensure any substitute also holds AEC-Q101 qualification if automotive reliability is required.
