BZB84-C36-QR

Overview

The Nexperia BZB84-C36-QR is a dual voltage regulator diode in the BZB84-Q series, housed in an SOT23 surface-mount 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 approximately ±5% tolerance. Total power dissipation is rated at 300 mW per device, while non-repetitive peak reverse power dissipation reaches 40 W per diode. Qualified under AEC-Q101 for automotive applications, it operates within a junction temperature range of -55 °C to +150 °C.

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 demanding automotive environments
• Offers normalized E24 working voltage range from 2.4 V to 75 V with specific tolerance series

Applications

• General regulation functions
• Automotive electronic circuits requiring qualified discrete semiconductors

Procurement Notes

Verify the exact ordering suffix and marking code PJ against the official Nexperia BZB84-Q datasheet before procurement. Confirm that the dual common anode topology matches the circuit design requirements, as this differs from single-diode alternatives. Ensure compliance with AEC-Q101 qualification if the application mandates automotive-grade reliability standards.

Selection Notes

Select the BZB84-C36-QR when a dual Zener solution with a shared anode is required in a small SMD footprint. The 'C' suffix indicates approximately ±5% voltage tolerance, suitable for general-purpose regulation where tighter precision is not critical. Consider the 300 mW total power dissipation limit and thermal resistance characteristics for PCB layout planning.

Part Context

This component belongs to the Nexperia BZB84-Q series, which comprises 74 types of dual voltage regulator diodes. The series covers nominal working voltages from 2.4 V to 75 V across two tolerance grades: B (±2%) and C (approximately ±5%). All variants share the same SOT23 plastic package and AEC-Q101 automotive qualification.

Replacement Considerations

Direct functional substitutes within the same family include BZB84-B36-QR for tighter ±2% tolerance or other BZB84-Q series dual Zeners with different voltage ratings. Single-diode equivalents like BZX84-C36-QR require separate components for dual-channel functionality.
