BZB84-C3V6-QR

Overview

The Nexperia BZB84-C3V6-QR is a dual voltage regulator diode in the BZB84-Q series, housed in an SOT-23 (TO-236AB) surface-mount package. It features a dual common anode configuration with two independent cathodes. The nominal Zener voltage is 3.6 V with a ±5% tolerance range of 3.40 V to 3.80 V at IZ = 5 mA. Total power dissipation is 300 mW, while non-repetitive peak reverse power dissipation reaches 40 W per diode. Differential resistance is 90 Ω maximum at IZ = 5 mA and 5 Ω at IZ = 1 mA. Reverse current is 600 μA maximum at IZ = 5 mA. Diode capacitance is 1 pF maximum at IZ = 5 mA. Operating temperature ranges from -55 °C to +150 °C.

Feature Summary

• Dual common anode configuration providing two independent regulation channels in a single compact package.
• Qualified according to AEC-Q101 standards for automotive application reliability.
• Small plastic SOT-23 package suitable for automated surface-mounted design processes.

Applications

• General voltage regulation functions
• Automotive electronic circuits

Procurement Notes

Verify the specific suffix 'QR' against official Nexperia documentation to confirm reel packaging specifications and tape-and-reel dimensions. Ensure the component matches the BZB84-Q series data sheet revision 2 dated April 10, 2024, for accurate electrical parameters. Confirm that the supplier provides traceability documents consistent with automotive qualification requirements.

Selection Notes

Select this component when a dual-channel voltage reference is required within space-constrained designs. The dual common anode topology allows for efficient use of board area compared to discrete single diodes. Verify that the 300 mW total power dissipation rating accommodates the thermal environment of the target application without exceeding junction temperature limits.

Part Context

This device belongs to the BZB84-Q series, which offers 74 types with nominal working voltages from 2.4 V to 75 V. The series includes three tolerance variants: BZX84-A (±1%), BZX84-B (±2%), and BZX84-C (approximately ±5%). All variants share the same SOT-23 package and automotive qualification profile.

Replacement Considerations

Direct substitutes include other BZB84-Q series parts with identical dual common anode configurations. Single-diode equivalents like the BZX84-C3V6 require two separate components to replicate the dual functionality. Verify pinout compatibility when substituting with non-Nexperia dual Zener diodes in the SOT-23 package.
