PZU3.3DB2,115

Overview

The PZU3.3DB2,115 is a dual isolated general-purpose Zener diode from the PZUxDB2 series, housed in an SOT353 (SC-88A) surface-mounted package with five leads. It features two independent diodes within a single compact component. The nominal working voltage is 3.3 V with a tolerance of approximately ±2%. Key electrical parameters include a maximum reverse current of 5 μA at IZ = 0.5 mA and a differential resistance of 95 Ω at IZ = 5 mA. The device supports a total power dissipation of 250 mW and is qualified to AEC-Q101 standards for automotive applications.

Feature Summary

• Dual isolated diode configuration allowing independent operation within a single package
• High precision voltage regulation with approximately ±2% tolerance series
• Automotive-grade reliability compliant with AEC-Q101 qualification standards
• Compact SOT353 surface-mount package suitable for space-constrained designs

Applications

• General voltage regulation functions
• Automotive electronic circuits requiring AEC-Q101 qualified components
• Industrial control systems needing precise voltage references

Procurement Notes

Verify the specific ordering suffix matches the required packing quantity and halogen-free status. Confirm the manufacturer source is Nexperia, as the NXP standard product business was transferred. Ensure the component version aligns with the latest datasheet revision to guarantee compatibility with current manufacturing processes and quality standards.

Selection Notes

Select this component when a dual Zener solution is required in a minimal footprint. The 3.3 V nominal voltage suits logic level referencing and protection circuits. Consider the low reverse current and tight tolerance for precision applications. Verify thermal management requirements against the specified junction-to-ambient resistance values for the target PCB layout.

Part Context

This part belongs to the PZUxDB2 series, which offers various nominal voltages ranging from 2.7 V to 24 V. All variants share the same SOT353 package and pinout configuration, differing primarily in their Zener voltage characteristics. The series provides a scalable discrete solution for voltage reference and protection needs across multiple industries.

Replacement Considerations

Direct substitutes must match the SOT353 package, dual isolated topology, and 3.3 V nominal voltage with similar tolerance. Verify that alternative components meet AEC-Q101 requirements if used in automotive contexts. Check pinout compatibility to ensure direct replacement without PCB redesign.
