BZB84-C5V1-QR

Overview

The Nexperia BZB84-C5V1-QR is a dual voltage regulator diode in the BZB84-Q series, housed in an SOT23 surface-mounted package. It features a dual common anode configuration with two independent cathodes. The nominal Zener voltage is 5.1 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. The device operates within a junction temperature range of -55 °C to +150 °C and is qualified according to AEC-Q101 for automotive applications.

Feature Summary

• Dual common anode configuration providing two independent regulation channels in a single compact package.
• Qualified according to AEC-Q101 standards, making it suitable for demanding automotive electronic environments.
• Small plastic SOT23 package designed for efficient surface-mounted assembly processes.

Applications

• General voltage regulation functions
• Automotive circuit protection and reference voltage generation

Procurement Notes

Verify the specific suffix against official Nexperia documentation to confirm package variant and tape-and-reel specifications. Ensure that the ordering code matches the required tolerance series and packaging format for your production line. Cross-reference the marking code UH% with the datasheet to validate component authenticity upon receipt.

Selection Notes

Select this component when a dual-channel voltage reference is required in a minimal footprint. The C-series designation indicates a standard ±5 % voltage tolerance, which suits general-purpose applications rather than high-precision requirements. Confirm that the 300 mW total power dissipation meets the thermal constraints of the target PCB layout.

Part Context

This part belongs to the BZB84-Q series, which offers a wide working voltage range from 2.4 V to 75 V. The series includes both B (±2 %) and C (±5 %) tolerance variants. All parts in this family share the same SOT23 physical dimensions and pinout, allowing for design flexibility across different voltage requirements within automotive and industrial systems.

Replacement Considerations

Direct substitutes include other BZB84-Q series dual Zener diodes with identical pinouts, such as BZB84-B5V1-QR or BZB84-C5V6-QR. Verify that any replacement maintains the same AEC-Q101 qualification status and thermal characteristics if used in automotive contexts.
