BZX84B5V6-AQ

Single Zener Diodes Overview

The BZX84B5V6-AQ is a single SMD planar Zener diode manufactured by Diotec Semiconductor. It operates within the BZX84B series, featuring a nominal Zener voltage of 5.6 V with a tight tolerance of ±2%. The device is housed in an SOT-23 (TO-236) surface-mount package and supports a total power dissipation of 300 mW at 25°C ambient temperature. It is qualified to AEC-Q101 automotive standards. Key electrical characteristics include a maximum dynamic resistance of less than 40 Ω at a test current of 5 mA, a reverse leakage current of 1 µA at 1 V, and a junction temperature range of -50°C to +150°C.

Single Zener Diodes Feature Summary

• Provides sharp Zener voltage breakdown characteristics for precise regulation.
• Features low leakage current to minimize standby power consumption.
• Compliant with RoHS directives without exemptions and REACH regulations.

Single Zener Diodes Applications

• Voltage stabilization circuits
• Voltage regulator designs

Single Zener Diodes Procurement Notes

Verify that the specific part number suffix matches the required qualification level. The '-AQ' suffix indicates AEC-Q101 qualified status, which differs from the standard commercial grade or the '-Q' compliant variant. Confirm mechanical compatibility with the target PCB footprint and ensure thermal management aligns with the specified power dissipation limits under actual operating conditions.

Single Zener Diodes Selection Notes

Select this component when a high-precision reference voltage is required in space-constrained applications. The ±2% tolerance offers tighter accuracy than standard ±5% variants. Ensure the design accounts for the negative temperature coefficient inherent to Zener voltages below approximately 6 V. Verify that the maximum Zener current rating is not exceeded during transient load conditions.

Single Zener Diodes Part Context

This component belongs to the BZX84B series of SMD Planar Zener Diodes from Diotec Semiconductor. The series covers a wide voltage range from 2.4 V to 47 V. The 'B' designation specifically denotes the ±2% tolerance grade, distinguishing it from the standard 'C' grade which typically offers ±5% tolerance. The series is designed for general-purpose commercial and industrial applications requiring reliable voltage regulation.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering SOT-23 packaged Zener diodes with 5.6 V nominal voltage and ±2% tolerance. Ensure any substitute meets the same AEC-Q101 qualification if automotive reliability is required. Verify that the replacement's dynamic resistance and leakage current specifications are equal to or better than the original datasheet values.
