BZB84-B13-QR

Overview

The Nexperia BZB84-B13-QR is a dual voltage regulator diode in the BZB84-Q series, housed in an SOT23 surface-mounted plastic package. It features a dual common anode configuration with two independent cathodes. The device provides a nominal Zener voltage of 13 V with a tight tolerance of ±2%. Key electrical characteristics include a maximum total power dissipation of 300 mW and a non-repetitive peak reverse power dissipation of 40 W per diode. The component operates within a junction temperature range of -55 °C to +150 °C and is qualified according to AEC-Q101 standards for automotive applications.

Feature Summary

• Dual common anode configuration enabling compact circuit designs
• AEC-Q101 qualification suitable for automotive environments
• Tight voltage tolerance series available for precision regulation

Applications

• General voltage regulation functions
• Automotive electronic circuits requiring robust discrete semiconductors

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current catalog to ensure correct packaging and tape-and-reel specifications. Confirm that the selected variant matches the required voltage tolerance class for the intended design. Cross-reference the marking code table to validate physical identification on the component body during incoming inspection.

Selection Notes

Select this component when a dual-diode solution is required to save board space compared to single packages. Ensure the application current remains within the specified limits to maintain the ±2% voltage accuracy. Consider the thermal resistance values if multiple units are placed in close proximity on the PCB layout.

Part Context

This part belongs to the BZB84-Q series, which offers a wide range of nominal working voltages from 2.4 V to 75 V. The series includes both B (±2%) and C (±5%) tolerance options. All variants share the same SOT23 footprint and pinout, facilitating design flexibility across different voltage requirements within the same product family.

Replacement Considerations

Direct substitutes within the same series include BZB84-C13-Q for looser tolerance or other BZB84-Bxxx-Q variants for different voltage levels. Verify pin compatibility and thermal performance before swapping with generic dual Zener diodes from other manufacturers.
