BZB84-B16,215

Overview

The Nexperia BZB84-B16,215 is a dual Zener diode in a SOT-23 (TO-236AB) plastic surface-mounted package. It features a dual common anode configuration with two independent cathodes. The nominal Zener voltage is 16 V with a ±2% tolerance series designation. Key electrical parameters include a total power dissipation of 300 mW, a maximum reverse current of 40 μA at IZ=5 mA, and a differential resistance of 11.2 Ω. The device operates within a junction temperature range of -55 °C to +150 °C and supports non-repetitive peak reverse currents up to 1.5 A.

Feature Summary

• Dual common anode configuration for compact circuit design
• Automotive qualification compliant with AEC-Q101 standards
• High precision voltage regulation with ±2% tolerance option
• Small SOT-23 plastic package suitable for surface-mount applications

Applications

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

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 standards if used in vehicle electronics. Cross-reference the marking code 'PT' to validate authenticity upon receipt.

Selection Notes

Select this component when a dual Zener configuration with a common anode is required in a small footprint. The ±2% tolerance variant provides tighter voltage accuracy compared to standard options. Consider the thermal resistance characteristics and total power dissipation limits relative to the expected operating ambient temperature and PCB copper area.

Part Context

This part belongs to the BZB84 series of general-purpose dual Zener diodes manufactured by Nexperia. The series offers a wide working voltage range from 2.4 V to 75 V in the SOT-23 package. The BZB84-B16 specifically addresses applications requiring precise 16 V regulation in a space-constrained surface-mount environment.

Replacement Considerations

Direct pin-compatible substitutes within the same series include BZB84-C16,215 for ±5% tolerance requirements. Other Nexperia dual Zener diodes in SOT-23 packages may serve as functional alternatives if voltage ratings and configurations align.
