BZB84-C30-QR

Overview

The Nexperia BZB84-C30-QR is a dual voltage regulator diode in the BZB84-Q series, housed in an SOT23 surface-mount package. It features a common anode configuration with two independent cathodes. The device provides a nominal Zener voltage of 30 V with a tolerance of approximately ±5%. Key electrical parameters include a total power dissipation of 300 mW and a non-repetitive peak reverse power dissipation of 40 W per diode. The component operates within a junction temperature range of -55 °C to +150 °C and is qualified according to AEC-Q101 standards for automotive applications.

Feature Summary

• Dual common anode configuration allowing independent regulation from two cathodes
• Qualified according to AEC-Q101 for automotive reliability
• Compact SOT23 plastic package suitable for high-density surface-mounted designs

Applications

• General regulation functions
• Automotive electronic circuits requiring dual voltage references

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current catalog to ensure correct packaging and tape-and-reel specifications. Confirm that the AEC-Q101 qualification status aligns with the target automotive application requirements before finalizing procurement orders.

Selection Notes

Select this component when a dual-diode solution is required in a single SOT23 footprint. The C-series tolerance of approximately ±5% suits general-purpose regulation where tighter precision is not critical. Ensure the circuit design accounts for the 300 mW total power dissipation limit across both diodes.

Part Context

This part belongs to the BZB84-Q series, which offers a wide range of nominal working voltages from 2.4 V to 75 V. The series includes both B (±2%) and C (±5%) tolerance options, providing flexibility for various voltage reference and protection needs in compact electronic designs.

Replacement Considerations

Direct functional substitutes within the same series include BZB84-B30-QR for tighter tolerance or other BZB84-Q variants for different voltage levels. Cross-package replacements require verifying pin compatibility and thermal characteristics.
