BZB84-B22,215

Overview

The Nexperia BZB84-B22,215 is a dual Zener diode in a SOT-23 (TO-236AB) surface-mounted package. It features a dual common anode configuration with two independent cathodes and one shared anode pin. The nominal Zener voltage is 22 V with a ±2% tolerance. Total power dissipation is 300 mW per device. Key electrical parameters include a maximum reverse current of 55 µA at IZ=5 mA, a differential resistance of 250 Ω, and a temperature coefficient ranging from 15.4 to 16.4 mV/K. The component supports a junction temperature up to 150 °C and is AEC-Q101 qualified.

Feature Summary

• Dual common anode configuration for compact circuit design
• AEC-Q101 qualified for automotive applications
• Small plastic SMD package suitable for high-density layouts

Applications

• General regulation functions

Procurement Notes

Verify the specific suffix '215' against the manufacturer's latest documentation to confirm manufacturing origin details. Ensure the ordering code matches the required ±2% tolerance series ('B') and the 22 V nominal voltage rating. Cross-reference the marking code 'PV' on the physical component to validate authenticity and correct part identification before integration into production.

Selection Notes

Select this component when a dual Zener solution with a common anode is required in a small footprint. The ±2% tolerance provides tighter voltage accuracy compared to the standard ±5% series. Consider the 300 mW total power dissipation limit and the specific temperature coefficient range for thermal stability requirements in the target application environment.

Part Context

This part belongs to the Nexperia BZB84 series of general-purpose dual Zener diodes. The series offers a wide working voltage range from 2.4 V to 75 V in the SOT-23 package. The 'B' suffix indicates the ±2% tolerance variant, while 'C' denotes ±5%. The series is designed for surface-mount assembly and includes AEC-Q101 qualification for automotive use cases.

Replacement Considerations

Direct substitutes within the same family include BZB84-C22,215, which shares the same package and configuration but has a wider ±5% voltage tolerance. Other BZB84 variants with different nominal voltages may be used if the circuit design allows for voltage adjustment.
