PZU14DB2,115

Overview

The PZU14DB2,115 is a dual Zener diode array manufactured by Nexperia USA Inc. It features two independent Zener diodes housed in a compact SOT-353 (SC-70-5) surface-mount package. The nominal Zener voltage is 14 V with a tight tolerance of ±2%. Each diode supports a maximum power dissipation of 275 mW at an ambient temperature of 25°C. The device operates within a junction temperature range of -65°C to +150°C and is qualified under the AEC-Q101 standard for automotive applications.

Feature Summary

• Dual configuration providing two independent Zener diodes in a single compact package
• High precision voltage regulation with ±2% tolerance for stable reference applications
• Automotive grade qualification ensuring reliability in demanding environments
• Low leakage current characteristics suitable for sensitive circuit protection

Applications

• Voltage reference circuits requiring precise potential levels
• Over-voltage protection for signal lines in automotive systems
• Clamping applications in high-density digital logic interfaces
• General-purpose voltage regulation in consumer electronics

Procurement Notes

Verify the specific ordering code PZU14DB2,115 against official Nexperia documentation to confirm availability status and lead times. Ensure compatibility with AEC-Q101 requirements if used in automotive designs. Check for any recent Product Change Notifications regarding packaging or manufacturing site updates before finalizing procurement plans.

Selection Notes

Select this component when space constraints require dual Zener functions in a small outline package. The ±2% tolerance makes it suitable for applications needing tighter voltage accuracy than standard ±5% devices. Consider the 275 mW power rating and thermal derating curves for high-temperature operation scenarios.

Part Context

This part belongs to the Nexperia PZUxDB2 series of dual Zener diodes. The series offers various voltage options and tolerances, designed for compact board layouts. The 'B' suffix typically indicates the ±2% tolerance variant, distinguishing it from standard tolerance versions within the broader Zener diode portfolio.

Replacement Considerations

Direct replacements must match the SOT-353 package, 14 V nominal voltage, ±2% tolerance, and dual independent configuration. Verify that alternative parts meet the same AEC-Q101 qualification level and thermal specifications for seamless integration.
