BZB84-B39,215

Overview

The Nexperia BZB84-B39,215 is a dual Zener diode in a SOT-23 (TO-236AB) surface-mount package. It features a nominal working voltage of 39 V with a ±2% tolerance series designation. The device has a total power dissipation of 300 mW and operates within an ambient temperature range of -55 °C to +150 °C. Key electrical characteristics include a maximum reverse current of 0.05 µA at IZ=2 mA, a differential resistance of 130 Ω, and a non-repetitive peak reverse power dissipation of 40 W.

Feature Summary

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

Applications

• General regulation functions

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm manufacturing origin and compliance status. Ensure the component matches the required voltage tolerance class before integration into production designs.

Selection Notes

Select this variant when a precise 39 V reference with tight tolerance is required. The dual common anode structure allows independent control of two regulated outputs from a single shared ground connection.

Part Context

This component belongs to the BZB84 series of general-purpose dual Zener diodes. The series offers a wide range of nominal voltages from 2.4 V to 75 V across different tolerance grades.

Replacement Considerations

Direct substitutes within the same series include BZB84-C39,215, which shares the package but differs in voltage tolerance specifications.
