BZB84-C47-QR

Overview

The BZB84-C47-QR is a dual voltage regulator diode from the Nexperia BZB84-Q series, housed in a SOT23 small Surface-Mounted Device plastic package. It features a dual common anode configuration and is qualified according to AEC-Q101 for automotive applications. The device offers a nominal working voltage of 47 V with approximately ±5 % tolerance. Key electrical parameters include a total power dissipation of ≤ 300 mW per device and a non-repetitive peak reverse power dissipation of ≤ 40 W per diode. The forward voltage is typically 0.9 V at 10 mA, with a junction temperature range up to 150 °C.

Feature Summary

• Dual common anode configuration within a compact SOT23 surface-mounted package
• Qualified according to AEC-Q101 standards for automotive application suitability
• Provides general regulation functions with low differential resistance

Applications

• General regulation functions
• Automotive electronic circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product data sheet to ensure compatibility with required tolerance grades and automotive qualification standards. Confirm that the SOT23 package dimensions align with the intended PCB footprint design. Cross-reference the marking code PM% with physical samples to authenticate the component origin and prevent counterfeit risks during assembly.

Selection Notes

Select this component when a dual Zener configuration with a shared anode is required in space-constrained designs. The C-series designation indicates an approximate ±5 % voltage tolerance, suitable for standard regulation tasks where tighter precision is not critical. Ensure the operating current remains within limits to maintain the specified temperature coefficient and reverse leakage characteristics for stable performance.

Part Context

This part belongs to the BZB84-Q series, which comprises 74 types of dual voltage regulator diodes ranging from 2.4 V to 75 V. All variants share the same SOT23 package and AEC-Q101 qualification, differing primarily in breakdown voltage and tolerance grade (B or C). The series provides a standardized solution for high-density circuit designs requiring multiple regulated voltage references.

Replacement Considerations

Direct substitutes within the same family include other BZB84-Q dual diodes with identical pinout and package. Single-channel equivalents like the BZX84-Q series may replace individual sections but require separate components for dual functionality. Verify thermal resistance and power dissipation ratings match the original design constraints when considering alternative packages.
