BZB984-C7V5,115

Overview

The Nexperia BZB984-C7V5,115 is a voltage regulator double diode housed in an ultra-small SOT663 plastic surface-mounted device package. It provides dual Zener regulation with a nominal working voltage of 7.5 V and a tolerance of approximately 5%. The component supports a total power dissipation of up to 425 mW when both diodes are loaded at temperatures ≤ 25 °C, or 265 mW for single-diode operation. Key electrical characteristics include a maximum forward voltage of 0.9 V at 10 mA, a non-repetitive peak reverse current of 150 A (at 100 µs pulse), and a junction temperature limit of 150 °C.

Feature Summary

• Dual Zener diodes integrated into a compact three-lead SOT663 package for space-constrained designs.
• Provides general voltage regulation functions with standardized E24 series nominal voltages.
• Capable of handling high non-repetitive surge currents for transient protection applications.

Applications

• General regulation functions
• ESD and surge protection

Procurement Notes

Verify the specific ordering suffix matches the required tape-and-reel quantity configuration before finalizing procurement orders. Confirm that the application environment remains within the specified non-automotive qualification limits, as this product lacks automotive reliability testing. Ensure thermal management strategies account for the stated thermal resistance values under actual PCB mounting conditions.

Selection Notes

Select this component when dual independent voltage references or clamping paths are required in a minimal footprint. The SOT663 package is suitable for high-density circuit boards where standard discrete packages exceed available space. Consider the 5% tolerance band for applications requiring moderate precision without the cost of tighter grading options.

Part Context

This part belongs to the BZB984 series of low-power voltage regulator double diodes manufactured by Nexperia. The series offers various nominal voltages ranging from 2.4 V to 15 V, all sharing the same SOT663 package outline and pinning configuration. It serves as a compact alternative to using two separate single Zener diodes in voltage reference or protection circuits.

Replacement Considerations

Direct functional replacements must match the SOT663 package, 7.5 V nominal voltage, and dual-diode configuration. Verify that any substitute component meets the 425 mW total power dissipation requirement and maintains compatible thermal resistance characteristics for the intended PCB layout.
