BZX84-C18-QVL

Single Zener Diodes Overview

The Nexperia BZX84-C18-QVL is a low-power voltage regulator diode from the BZX84-Q series, housed in a SOT23 (TO-236AB) surface-mounted plastic package. It provides a nominal Zener voltage of 18 V with an approximate ±5% tolerance. The device features a total power dissipation of 250 mW and operates within a junction temperature range of -55 °C to +150 °C. Qualified according to AEC-Q101, it supports automotive applications with a non-repetitive peak reverse power dissipation of up to 40 W.

• Compact SOT23 surface-mount packaging

Single Zener Diodes Applications

• General regulation functions

Single Zener Diodes Procurement Notes

Verify the specific suffix 'QVL' against official Nexperia documentation to confirm reel specifications and tape-and-reel dimensions. Ensure the component meets the required AEC-Q101 qualification standards for the intended automotive environment. Cross-reference the marking code 'Y6' on the package to validate authenticity and correct part identification before integration into production lines.

Single Zener Diodes Selection Notes

Select this component when a stable 18 V reference is needed in space-constrained designs requiring automotive-grade reliability. The SOT23 package suits high-density PCB layouts. Consider the ±5% tolerance and thermal resistance characteristics for circuits where precise voltage regulation and heat dissipation are critical factors in the overall system design.

Single Zener Diodes Part Context

This part belongs to the BZX84-Q series, which offers normalized E24 breakdown voltages ranging from 2.4 V to 75 V. The series includes three tolerance variants: ±1% (BZX84-A), ±2% (BZX84-B), and approximately ±5% (BZX84-C). All variants share the same small SOT23 footprint and are designed for general-purpose voltage regulation tasks.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other BZX84-C18-Q parts from Nexperia or equivalent 18 V Zener diodes in SOT-23 packages from other manufacturers, provided they meet AEC-Q101 requirements and match the 250 mW power dissipation rating.
