• AEC-Q101 qualification suitable for automotive environments
• Small plastic SMD package optimized for high-density layouts

Applications

• General regulation functions
• Voltage reference circuits
• Over-voltage protection

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm manufacturing origin and compliance status. Ensure the procurement channel sources directly from authorized distributors or the manufacturer to guarantee authenticity. Cross-reference the part number with the latest product data sheet to confirm current production status and any potential obsolescence notices before finalizing purchase orders.

Selection Notes

Select this component when a dual Zener configuration with a 33 V nominal voltage is required in a small footprint. The ±5% tolerance makes it suitable for general-purpose regulation where tight precision is not critical. Consider the 300 mW power dissipation limit and thermal resistance values during PCB layout planning to ensure reliable operation under expected load conditions.

Part Context

This part belongs to the Nexperia BZB84 series, which comprises 74 types of dual Zener diodes ranging from 2.4 V to 75 V. The series offers both ±2% and ±5% tolerance options in the SOT-23 package. The BZB84-C33 variant specifically utilizes the C-series tolerance band, providing a wider voltage range compared to the B-series.

Replacement Considerations

Direct replacements within the same series include other BZB84-C variants with different voltage ratings. For identical specifications, verify availability of BZB84-C33 from alternative authorized distributors. Substituting with BZB84-B33 requires accounting for the tighter ±2% tolerance specification.
