PZU3.6B1A-QX

Single Zener Diodes Overview

The PZU3.6B1A-QX is a Zener voltage regulator diode manufactured by Nexperia USA Inc., designed for general-purpose regulation functions in compact surface-mounted designs. It features a nominal Zener voltage of 3.6 V with a tight tolerance series B1, providing approximately ±2% accuracy. The device operates within a wide working voltage range and is characterized by low reverse current and small plastic packaging suitable for high-density circuit applications.

Single Zener Diodes Feature Summary

• Tight voltage tolerance of approximately ±2% for precise regulation
• Low reverse leakage current for efficient operation
• Compact SOD323 (SC-76) surface-mount package design

Single Zener Diodes Applications

• General voltage regulation functions
• Reference voltage generation in low-power circuits
• Over-voltage protection in signal lines

Single Zener Diodes Procurement Notes

Verify the specific suffix 'QX' against official Nexperia documentation to confirm automotive qualification status and tape-and-reel packaging details. Ensure compatibility with standard SOD323 footprints during PCB layout. Confirm availability as this variant may have limited distribution compared to standard commercial grades.

Single Zener Diodes Selection Notes

Select this component when a precise 3.6 V reference is required with minimal voltage drift. The ±2% tolerance makes it suitable for applications demanding higher accuracy than standard ±5% Zener diodes. Consider the low reverse current characteristics for battery-powered or low-quiescent-current designs.

Single Zener Diodes Part Context

This part belongs to Nexperia's PZU16B1A series of general-purpose Zener diodes. These devices are engineered for cost-effective voltage regulation in space-constrained environments. The series offers various voltage options within the E24 range, supporting diverse industrial and consumer electronics requirements.

Single Zener Diodes Replacement Considerations

Direct substitutes include other Nexperia Zener diodes with similar voltage and tolerance, such as PZU3.6B1A without the QX suffix for non-automotive use. Verify pinout compatibility with SOD323 packages before substitution.
