BZB84-C4V7,215

Overview

The Nexperia BZB84-C4V7,215 is a dual Zener diode in a SOT-23 (TO-236AB) surface-mount package. It features a dual common anode configuration with two independent cathodes and one shared anode. The nominal Zener voltage is 4.7 V with a ±5% tolerance. Total power dissipation is 300 mW per device. Key electrical parameters include a maximum reverse leakage current of 3 µA at IZ=1 mA, a differential resistance of 80 Ω at IZ=5 mA, and a forward voltage of 0.9 V at IF=10 mA. The junction temperature range is -55 °C to +150 °C.

Feature Summary

• Dual common anode configuration for compact circuit design
• Automotive grade qualification compliant with AEC-Q101 standards
• Small plastic SMD package suitable for high-density layouts

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to confirm manufacturing origin and compliance status. Ensure the component matches the required automotive qualification level if used in vehicle electronics. Cross-reference the marking code 'UG' on the physical device to confirm authenticity and correct voltage rating before integration into production assemblies.

Selection Notes

Select this component when a dual Zener solution is required within a single SOT-23 footprint. The C-series offers approximately ±5% tolerance, suitable for general-purpose applications where tight voltage precision is not critical. Consider the thermal resistance characteristics and total power dissipation limits relative to the ambient operating conditions of the target PCB layout.

Part Context

This part belongs to the BZB84 series of dual Zener diodes manufactured by Nexperia. The series provides various breakdown voltages ranging from 2.4 V to 75 V in normalized E24 values. The BZB84-C variant specifically denotes the approximate ±5% tolerance band, distinguishing it from the tighter ±2% B-series options within the same package family.

Replacement Considerations

Direct substitutes within the same series include other BZB84-Cxxxx variants with different voltage ratings. For single-diode equivalents, the BZX84-C4V7 may be considered if the dual configuration is not required, though pinout compatibility must be verified.
