BZB84-B15,215

Overview

The Nexperia BZB84-B15,215 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 pin. The nominal Zener voltage is 15 V with a ±2% tolerance. Total power dissipation is 300 mW per device. Key electrical parameters include a maximum reverse current of 50 μA at IZ=5 mA, a differential resistance of 200 Ω, and a temperature coefficient ranging from 9.2 to 13.0 mV/K. Non-repetitive peak reverse current is 75 A for 100 μs pulses.

Feature Summary

• Dual common anode configuration allows independent regulation using two Zener junctions within a single compact package.
• Qualified under the AEC-Q101 standard for automotive applications, ensuring reliability in demanding environments.
• Small plastic SMD package design supports high-density circuit layouts and automated surface-mount assembly processes.

Applications

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

Procurement Notes

Verify the specific ordering suffix matches the required manufacturing origin and lot traceability. Confirm that the component status remains active production before finalizing designs. Ensure compliance with RoHS directives as indicated in the datasheet. Cross-reference the marking code 'VW' to validate physical authenticity upon receipt.

Selection Notes

Select this part when a dual Zener solution is required in a minimal footprint. The ±2% tolerance series provides tighter voltage accuracy compared to the ±5% variant. Consider the thermal resistance characteristics for heat dissipation requirements in enclosed spaces. Verify that the operating voltage range aligns with the system's nominal supply levels.

Part Context

This component belongs to the BZB84 series of general-purpose dual Zener diodes manufactured by Nexperia. The series offers a wide range of nominal working voltages from 2.4 V to 75 V. It is designed for use in small-scale, high-density electronic circuits requiring reliable voltage stabilization.

Replacement Considerations

Direct substitutes within the same series include BZB84-C15,215, which shares the same package and configuration but offers a wider ±5% voltage tolerance. Other BZB84 variants may be considered if voltage ratings differ, provided the pinout and thermal constraints remain compatible.
