BZB984-C13,115

Overview

The BZB984-C13,115 is a voltage regulator double diode from the Nexperia BZB984 series, housed in an ultra-small SOT663 plastic surface-mounted package. It features two independent Zener diodes sharing a common anode (Pin 3), with cathodes on Pins 1 and 2. The nominal working voltage is 13 V, with a tolerance of approximately ±5%. Key electrical parameters include a maximum forward voltage of 0.9 V at 10 mA, a total power dissipation of 425 mW when both diodes are loaded, and a non-repetitive peak reverse current of 80 A for a 100 µs pulse. The device operates within a junction temperature range of -55 °C to +150 °C.

Feature Summary

• Dual Zener configuration in a compact SOT663 package suitable for high-density circuit designs
• Approximately 5% working voltage tolerance for precise regulation applications
• Common anode structure enabling efficient space-saving implementation

Applications

• General voltage regulation functions
• ESD protection circuits
• Surge protection applications

Procurement Notes

Verify the specific ordering suffix matches the required tape-and-reel quantity and packaging format. Confirm that the component meets the intended environmental operating conditions. Ensure the design accounts for the thermal resistance values provided in the datasheet to maintain safe junction temperatures during operation.

Selection Notes

Select this component when dual voltage references or protection channels are needed in minimal board space. The 13 V nominal rating suits applications requiring stable reference levels near this value. Consider the 425 mW total power dissipation limit when designing heat dissipation paths on the PCB footprint.

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 in the E24 series. All variants share the same SOT663 package and pinout, differing primarily in their Zener breakdown voltage specifications. The series is designed for low-power regulation tasks where size constraints are critical.

Replacement Considerations

Other members of the BZB984 series (e.g., BZB984-C12, BZB984-C15) offer identical packaging and pin configurations with different nominal voltages. Verify that alternative parts meet the specific voltage tolerance and power dissipation requirements of the original design.
