BZX84W-C30-QX

Single Zener Diodes Overview

The Nexperia BZX84W-C30-QX is a general-purpose Zener diode from the BZX84W-Q series, designed for automotive applications. It operates in a SOT-323 (SC-70) leadless surface-mount package with a nominal Zener voltage of 30 V and a tolerance of ±5%. The device supports a total power dissipation of 275 mW at 25 °C and functions within an ambient temperature range of -55 °C to +150 °C. Key electrical characteristics include a maximum reverse current of 50 nA, a differential resistance of 300 Ω, and a typical temperature coefficient of 26.6 mV/K.

Single Zener Diodes Feature Summary

• Qualified according to AEC-Q101 standards for automotive use
• Available in a very small SOT-323 (SC-70) leadless plastic package
• Offers wide working voltage range from 2.4 V to 75 V

Single Zener Diodes Applications

• General regulation functions
• High-frequency applications

Single Zener Diodes Procurement Notes

Verify that the ordering suffix '-QX' corresponds to the specific tape-and-reel packaging configuration required for your automated assembly line. Confirm that the component meets the AEC-Q101 qualification requirements for your target automotive application environment. Ensure the design accounts for the thermal resistance characteristics specified in the datasheet to maintain junction temperatures within safe limits during operation.

Single Zener Diodes Selection Notes

Select this component when a compact surface-mount Zener diode with automotive qualification is required. The ±5% tolerance variant is suitable for general regulation tasks where tighter precision is not critical. Consider the low capacitance and high-speed switching capabilities for high-frequency circuit designs. Evaluate the thermal performance against the expected power dissipation in the final PCB layout.

Single Zener Diodes Part Context

This part belongs to the BZX84W-Q series of voltage regulator diodes manufactured by Nexperia. The series provides various breakdown voltages from 2.4 V to 75 V in the SOT-323 package. The 'Q' designation indicates AEC-Q101 qualification, while the 'C' suffix specifies the ±5% voltage tolerance band. These diodes are intended for robust electronic systems requiring reliable voltage reference or protection.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same family include other BZX84W-C30-Q variants with different packaging options, such as cut-tape versions. Cross-series replacements like the standard BZX84W-C30 may be considered if automotive qualification is not mandatory, though package dimensions and electrical parameters should be verified for compatibility.
