PZU15DB2,115

Overview

The PZU15DB2,115 is a dual isolated general-purpose Zener diode housed in an SOT353 (SC-88A) surface-mounted package. It features a nominal working voltage of 15 V with a tolerance series B2 providing approximately ±2% accuracy. The device supports a total power dissipation of 250 mW and operates within an ambient temperature range of -55 °C to +150 °C. Key electrical characteristics include a maximum reverse current of 15 μA at 5 mA test current, a differential resistance of 80 Ω, and a non-repetitive peak reverse power dissipation of 40 W.

Feature Summary

• Dual isolated diode configuration for compact circuit design
• High precision tolerance series B2 for accurate voltage regulation
• Automotive-grade AEC-Q101 qualification for reliability
• Halogen-free dark-green plastic package suitable for surface mounting

Applications

• General regulation functions
• Voltage reference applications
• Automotive electronic circuits

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm packaging details and manufacturing origin. Ensure compatibility with SOT353 footprints during PCB layout. Confirm that the halogen-free DG variant designation aligns with environmental compliance requirements for the target assembly process.

Selection Notes

Select this component when precise voltage regulation is required in space-constrained designs. The dual isolated structure allows independent handling of two voltage references or protection paths within a single footprint. Consider the ±2% tolerance for applications demanding tight voltage stability without external trimming.

Part Context

This part belongs to the PZUxDB2 series of dual Zener diodes manufactured by Nexperia. The series offers various nominal voltages from 2.7 V to 24 V in the same SOT353 package. The 'B2' suffix denotes the specific tolerance class, while ',115' indicates the standard tape and reel packing method for automated assembly.

Replacement Considerations

Compatible substitutes within the same series include other PZUxDB2 variants with different voltage ratings but identical pinouts. Single Zener diodes in similar packages may require circuit redesign due to pin configuration differences. Verify thermal resistance and power dissipation limits when substituting with higher-power alternatives.
