BZB84-C9V1,215

Overview

The BZB84-C9V1,215 is a dual Zener diode from the Nexperia BZB84 series, housed in a SOT23 (TO-236AB) plastic surface-mounted package. It features a dual common anode configuration with two independent cathodes and one shared anode pin. The device provides a nominal working voltage of 9.1 V with a ±5% tolerance (indicated by the 'C' suffix). Key electrical parameters include a total power dissipation of 300 mW per device, a non-repetitive peak reverse power dissipation of 40 W, and a maximum junction temperature of 150 °C. The forward voltage is specified at a maximum of 0.9 V when tested at 10 mA.

Feature Summary

• Dual common anode configuration for compact circuit design
• AEC-Q101 qualified for automotive reliability standards
• Small SOT23 plastic package suitable for automated surface-mount assembly

Applications

• General regulation functions

Procurement Notes

Verify the specific ordering code BZB84-C9V1,215 against the manufacturer's current catalog to confirm availability and packaging details. Ensure that the component meets the required AEC-Q101 qualification status if intended for automotive applications. Cross-reference the marking code UR* to validate authenticity upon receipt.

Selection Notes

Select this component when a dual Zener solution with a common anode is required in a small footprint. The C-series designation indicates a standard 5% voltage tolerance, which is suitable for general-purpose regulation where tighter precision is not critical. Consider the 300 mW total power dissipation limit when designing thermal management for high-density PCB layouts.

Part Context

This part belongs to the BZB84 series of dual Zener diodes manufactured by Nexperia. The series offers a wide range of nominal voltages from 2.4 V to 75 V in both ±2% (B-series) and ±5% (C-series) tolerances. All variants share the same SOT23 package and dual common anode topology, allowing for consistent board layout across different voltage requirements within a single product family.

Replacement Considerations

Direct replacements must match the dual common anode configuration and SOT23 package. Other BZB84 series parts with different voltage ratings are pin-compatible. Verify that any substitute also holds AEC-Q101 qualification if automotive use is required.
