BZB84-B36-QR

Overview

The Nexperia BZB84-B36-QR is a dual voltage regulator diode in the BZB84-Q series, housed in an SOT23 surface-mounted package. It features a dual common anode configuration with two independent Zener diodes sharing a single anode terminal. The device provides a nominal working voltage of 36 V with a ±2% tolerance (Series B). Key electrical parameters include a total power dissipation of ≤300 mW and a non-repetitive peak reverse power dissipation of ≤40 W per diode. It operates within a junction temperature range of -55 °C to +150 °C and is qualified according to AEC-Q101 for automotive applications.

Feature Summary

• Dual common anode configuration integrating two independent Zener diodes in a compact SOT23 package.
• Qualified according to AEC-Q101 standards for use in automotive electronic applications.
• Offers normalized E24 working voltage range from 2.4 V to 75 V with specific tolerance series.

Applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current catalog to ensure compatibility with required packaging formats. Confirm that the component meets all relevant automotive qualification standards required for the target application environment before finalizing procurement decisions.

Selection Notes

Select this component when a dual Zener configuration with a shared anode is required in a small SMD footprint. Ensure the design accounts for the 300 mW total power dissipation limit across both diodes. Verify that the 36 V breakdown voltage aligns with the circuit's reference or regulation requirements.

Part Context

This part belongs to the Nexperia BZB84-Q series of dual voltage regulator diodes. The series offers various breakdown voltages from 2.4 V to 75 V in the SOT23 package. The 'B' suffix indicates a ±2% voltage tolerance, while the '-QR' suffix typically denotes reel packaging, though specific packaging details should be confirmed via official documentation.

Replacement Considerations

Direct replacements must match the dual common anode topology and SOT23-3 pinout. Compatible alternatives include other BZB84-Q series variants with similar voltage ratings or single-diode equivalents if the circuit design allows for modification of the common anode connection.
