BZB984-C3V3,115

Overview

The Nexperia BZB984-C3V3,115 is a voltage regulator double diode housed in an SOT663 ultra-small plastic surface-mounted device package. It contains two independent Zener diodes sharing a common anode (Pin 3), with cathodes on Pins 1 and 2. The nominal working voltage is 3.3 V with a tolerance of approximately 5%. Total power dissipation is rated at 425 mW when both diodes are loaded and 265 mW for single-diode operation at Tamb ≤ 25 °C. The junction temperature range extends from -55 °C to +150 °C.

Feature Summary

• Dual Zener configuration within a compact SOT663 package
• Common anode topology for simplified circuit design
• Low forward voltage drop characteristics

Applications

• General regulation functions
• ESD and surge protection

Procurement Notes

Verify the specific ordering suffix

Selection Notes

Select this component for applications requiring dual voltage references or protection channels in space-constrained designs. Ensure thermal management accounts for the 425 mW total dissipation limit under simultaneous loading conditions. Verify that the 3.3 V nominal breakdown voltage aligns with the target circuit requirements.

Part Context

This part belongs to the BZB984 series of voltage regulator double diodes. The series offers various nominal voltages ranging from 2.4 V to 15 V, all utilizing the same SOT663 package footprint. This allows designers to maintain consistent board layouts while adjusting voltage specifications across different product variants.

Replacement Considerations

Direct replacements must match the SOT663 package, common anode configuration, and 3.3 V Zener voltage. Verify pinout compatibility and thermal resistance values before substitution.
