BZB84-C27-QR

Overview

The Nexperia BZB84-C27-QR is a dual voltage regulator diode in the BZB84-Q series, housed in a SOT-23 surface-mount package. It features a common anode configuration with two independent cathodes. The nominal Zener voltage is 27 V with a tolerance of approximately ±5 %. Total power dissipation is limited to 300 mW at 25 °C ambient temperature. Forward voltage reaches a maximum of 0.9 V at 10 mA. Non-repetitive peak reverse power dissipation is rated at 40 W for pulses up to 300 μs. The device operates within a junction temperature range of -55 °C to +150 °C and is qualified according to AEC-Q101 standards.

Feature Summary

• Dual common anode configuration suitable for compact circuit designs
• AEC-Q101 qualification for automotive application reliability
• Small SOT-23 plastic package optimized for surface mounting

Applications

• General regulation functions
• Automotive electronic systems requiring qualified discrete semiconductors

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 voltage tolerance series, as the 'C' designation indicates approximately ±5 % tolerance rather than tighter grades. Confirm RoHS compliance status through the manufacturer's current product database before finalizing procurement orders.

Selection Notes

Select this component when a dual Zener configuration with a common anode is required in a small footprint. The BZB84-C27-QR provides a 27 V reference point with moderate tolerance suitable for general-purpose applications. Consider the 300 mW total power dissipation limit and thermal resistance characteristics during PCB layout planning to ensure operation remains within safe junction temperature limits under expected load conditions.

Part Context

This part belongs to the Nexperia BZB84-Q series, which offers a comprehensive range of dual voltage regulator diodes. The series includes various nominal working voltages from 2.4 V to 75 V across E24 values. Different tolerance grades are available, including the 'B' series for ±2 % and the 'C' series for approximately ±5 %. All variants share the same SOT-23 package and automotive qualification profile.

Replacement Considerations

Direct substitutes include other BZB84-Q series parts with identical pinout and package dimensions but different voltage ratings, such as BZB84-B27-QR for tighter tolerance requirements. Cross-brand replacements must match the SOT-23-3 footprint, common anode configuration, and minimum 300 mW power dissipation rating.
