BZB84-C15-QR

Overview

The BZB84-C15-QR is a dual voltage regulator diode from the Nexperia BZB84-Q series, housed in an SOT-23 surface-mounted plastic package. It features a dual common anode configuration with two independent cathodes. The device is qualified to AEC-Q101 standards for automotive applications. Key electrical parameters include a nominal working voltage of 15 V with approximately ±5% tolerance (range 13.8 V to 15.6 V). Total power dissipation is rated at ≤300 mW, while non-repetitive peak reverse power dissipation reaches ≤40 W. Differential resistance is 13.0 Ω at IZ=5 mA, and reverse current is 200 μA max.

Feature Summary

• Dual common anode configuration providing two independent regulation channels in a compact SOT-23 package.
• Qualified according to AEC-Q101 stress test standards for use in demanding automotive environments.
• Offers normalized E24 tolerance ranges including approximately ±5% for cost-effective general-purpose regulation.

Applications

• General voltage regulation functions
• Automotive electronic circuits requiring AEC-Q101 compliance

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm packaging details such as reel or cut tape specifications. Ensure the component matches the required automotive qualification level and package dimensions before finalizing procurement orders.

Selection Notes

Select this component when a dual-channel Zener solution is required within space-constrained designs. The C-series tolerance provides a balance between precision and cost. Verify that the 300 mW total power dissipation meets the thermal requirements of the target application environment.

Part Context

This part belongs to the BZB84-Q series, which expands Nexperia's portfolio of small-form-factor Zener diodes. The series offers various voltage options from 2.4 V to 75 V in both single and dual configurations, catering to high-density circuit designs in consumer and automotive sectors.

Replacement Considerations

Direct replacements within the same family include other BZB84-Q variants with different voltage ratings but identical pinouts and packages. Single-diode equivalents like the BZX84-C15-Q may be used if only one channel is needed, though the physical footprint remains compatible.
