PZU6.8B1A-QX

Single Zener Diodes Overview

The PZU6.8B1A-QX is a Zener voltage regulator diode manufactured by Nexperia, housed in the SOD323 (SC-76) surface-mounted device plastic package. It belongs to the B1 tolerance series, offering approximately ±2% voltage accuracy. The device supports a wide nominal working voltage range from 2.4 V to 51 V within the E24 series. Key electrical characteristics include a non-repetitive peak reverse power dissipation of up to 40 W and a total power dissipation limit of 320 mW. It features a low reverse current range and is qualified according to AEC-Q101 standards for automotive reliability.

Single Zener Diodes Feature Summary

• Automotive qualification compliant with AEC-Q101 standards
• High precision voltage regulation with approximately ±2% tolerance
• Compact SMD package suitable for high-density designs
• Optimized leakage current characteristics for fast switching

Single Zener Diodes Applications

Single Zener Diodes Procurement Notes

Verify the specific suffix 'QX' against official Nexperia documentation to confirm tape-and-reel packaging details. Ensure the component meets AEC-Q101 requirements for your target automotive application. Cross-reference the B1 tolerance designation to confirm the ±2% accuracy class matches your design specifications before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when precise voltage clamping is required in space-constrained automotive environments. The B1 series provides tighter tolerance than standard B series devices. Consider the SOD323 package size for PCB layout constraints. Verify thermal management capabilities given the 320 mW total power dissipation limit under operating conditions.

Single Zener Diodes Part Context

This part is part of Nexperia's general-purpose Zener diode portfolio designed for compact voltage regulation. It shares the SOD323 footprint with other variants in the PZU series but differs in breakdown voltage and tolerance class. The Q suffix indicates automotive qualification, distinguishing it from standard commercial grade equivalents.

Single Zener Diodes Replacement Considerations

Check for direct substitutes within the PZU6.8B1A family or equivalent AEC-Q101 qualified Zener diodes from other manufacturers. Ensure replacement parts match the SOD323 package and ±2% tolerance requirement.
