BZX384-B12-QX

Single Zener Diodes Overview

The BZX384-B12-QX is a low-power voltage regulator diode from the Nexperia BZX384-Q series, housed in an SOD-323 (SC-76) surface-mounted package. It provides a nominal Zener voltage of 12 V with a tight tolerance of ±2 %. The device supports a total power dissipation of up to 300 mW and operates within a junction temperature range of -65 °C to +150 °C. Qualified under AEC-Q101 standards, it is designed for robust performance in automotive environments.

Single Zener Diodes Procurement Notes

Verify the specific suffix against official Nexperia documentation to confirm tape-and-reel packaging configuration. Ensure the component meets the required AEC-Q101 qualification status for your target application environment before finalizing procurement specifications.

Single Zener Diodes Selection Notes

Select this component when precise voltage regulation is required in space-constrained designs. The ±2 % tolerance offers higher precision than standard variants. Confirm that the 300 mW power dissipation rating aligns with the thermal management capabilities of the intended PCB layout.

Single Zener Diodes Part Context

This part belongs to the BZX384-Q series, which includes 37 breakdown voltages ranging from 2.4 V to 75 V. The series is available in three tolerance grades: ±1 %, ±2 %, and approximately ±5 %. All variants share the same small SOD-323 footprint and automotive-grade qualification profile.

Single Zener Diodes Replacement Considerations

Cross-reference with other BZX384-B12-Q variants or equivalent AEC-Q101 qualified Zener diodes in SOD-323 packages. Verify pinout compatibility and ensure replacement parts meet the same ±2 % tolerance and 300 mW power dissipation requirements.
