BZX84-A5V1-QVL

Single Zener Diodes Overview

The Nexperia BZX84-A5V1-QVL is a low-power voltage regulator diode in the BZX84-Q series, housed in a SOT23 (TO-236AB) surface-mount package. It features a nominal Zener voltage of 5.1 V with a tight ±1 % tolerance. The device supports a total power dissipation of up to 250 mW and operates within an ambient temperature range of -55 °C to +150 °C. Qualified under AEC-Q101 for automotive applications, it offers a maximum reverse leakage current of 2 µA at 1 mA test current and a non-repetitive peak reverse power dissipation capability of 40 W.

Single Zener Diodes Feature Summary

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to ensure correct tape-and-reel configuration and marking codes. Confirm that the component meets all required environmental and reliability standards for the intended application before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when precise voltage reference stability is critical due to its narrow ±1 % tolerance band. Ensure the design accounts for the 250 mW power dissipation limit and verify thermal management requirements for operation near the upper temperature limits of the specified range.

Single Zener Diodes Part Context

This part belongs to the BZX84-Q series of low-power Zener diodes manufactured by Nexperia. The series provides various breakdown voltages from 2.4 V to 75 V across three tolerance grades: ±1 %, ±2 %, and approximately ±5 %. All variants share the same SOT23 footprint and automotive qualification profile.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other BZX84-A5V1-Q variants from Nexperia with different packaging suffixes, such as BZX84-A5V1-QR or BZX84-A5V1-QS, provided the electrical characteristics and pinout remain identical.
