BZX84W-C30-QF

Single Zener Diodes Overview

The Nexperia BZX84W-C30-QF is a general-purpose Zener diode from the BZX84W-Q series, housed in a SOT323 (SC-70) leadless surface-mounted plastic package. It provides a nominal Zener voltage of 30 V with a ±5% tolerance. The device features a total power dissipation of 275 mW and operates within an ambient temperature range of -55 °C to +150 °C. Key electrical characteristics include a maximum reverse current of 50 nA at 0.7 times the nominal Zener voltage, a differential resistance of 300 Ω at 2 mA, and a typical temperature coefficient of 26.6 mV/K.

Single Zener Diodes Feature Summary

Single Zener Diodes Procurement Notes

Verify the specific suffix 'QF' against official Nexperia documentation to confirm packaging details such as reel or cut tape configuration. Ensure the component meets AEC-Q101 requirements if intended for automotive use. Confirm that the ordering code matches the exact voltage tolerance and marking code specified in the datasheet before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a compact surface-mount Zener diode with automotive qualification is required. The BZX84W-C30-QF is suitable for designs needing a 30 V reference with moderate power handling. Consider the thermal resistance and package size constraints when choosing between this and other series members.

Single Zener Diodes Part Context

This part belongs to the BZX84W-Q series of voltage regulator diodes manufactured by Nexperia. The series includes 74 types with nominal working voltages ranging from 2.4 V to 75 V. These diodes are designed for general-purpose regulation and high-frequency applications, offering both ±2% and ±5% tolerance options in the SOT323 package.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same series include BZX84W-B30-Q (±2% tolerance) or other BZX84W-C variants with different voltage ratings. Verify pinout compatibility and thermal performance when replacing with non-Q series parts.
