BZB84-C13-QR

Overview

The Nexperia BZB84-C13-QR is a dual voltage regulator diode in a SOT23 surface-mounted package. It features a common anode configuration with two independent cathodes. The device provides a nominal Zener voltage of 13 V with a tolerance of approximately ±5 %. Total power dissipation is rated at 300 mW, while non-repetitive peak reverse power dissipation reaches 40 W per diode. Operating junction temperature ranges from -55 °C to +150 °C. The component is qualified according to AEC-Q101 standards for automotive applications.

Feature Summary

• Dual common anode configuration within a compact SOT23 plastic package
• Qualified according to AEC-Q101 standard for automotive use
• High non-repetitive peak reverse power dissipation capability

Applications

• General regulation functions

Procurement Notes

Verify the specific suffix 'QR' against official Nexperia documentation to confirm reel packaging specifications and tape-and-reel dimensions. Ensure the selected variant matches the required voltage tolerance series, as the 'C' designation indicates approximately ±5 % tolerance rather than tighter precision grades.

Selection Notes

Select this component when a dual-diode solution is required to save board space compared to single discrete units. The common anode topology simplifies circuit design for applications needing two regulated voltages or protection paths sharing a reference ground. Verify thermal constraints, as total power dissipation is limited to 300 mW across both diodes.

Part Context

This part belongs to the BZB84-Q series, which offers a comprehensive 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 functional substitutes include other BZB84-C13-Q variants from Nexperia with identical electrical characteristics but potentially different packaging suffixes. Single-channel alternatives like the BZX84-C13-Q require additional board space and separate components.
