BZB984-C15,115

Overview

The Nexperia BZB984-C15,115 is a dual voltage regulator diode array housed in an SOT-663 surface-mount package. It features a common anode configuration with two independent cathodes. The nominal Zener voltage is 15 V with a tolerance of ±5%. Total power dissipation is rated at 425 mW when both diodes are loaded and 265 mW for single-diode operation. Key electrical parameters include a maximum reverse leakage current of 50 nA, a differential resistance of 30 Ω, and a forward voltage of 0.9 V at 10 mA. The device operates within a temperature range of -65 °C to +150 °C.

Selection Notes

Select this component for applications requiring precise voltage reference or clamping in space-constrained environments. Ensure thermal management accounts for the 425 mW limit under simultaneous loading conditions. Verify that the 15 V breakdown voltage aligns with the target circuit requirements and that the SOT-663 footprint matches the PCB layout constraints.

Part Context

This part belongs to the BZB984 series, which offers a comprehensive range of nominal working voltages from 2.4 V to 15 V. All variants share the same SOT-663 package and common anode architecture, allowing designers to standardize on a single footprint while adjusting voltage levels via different type numbers within the E24 range.

Replacement Considerations

Other BZB984 series variants (e.g., BZB984-C13, BZB984-C11) are pin-compatible replacements if a different voltage rating is acceptable. Cross-series replacement requires verification of package dimensions, pinout compatibility, and thermal characteristics.
