BZB984-C5V1,115

Overview

The Nexperia BZB984-C5V1,115 is a voltage regulator double diode housed in an SOT663 ultra-small plastic surface-mounted package. It features a nominal working voltage of 5.1 V with approximately ±5% tolerance. The device provides a total power dissipation of up to 425 mW when both diodes are loaded and 265 mW for single-diode operation at Tamb ≤ 25 °C. Key electrical characteristics include a maximum forward voltage of 0.9 V at IF = 10 mA, a reverse current of 2 μA at VR = 2 V, and a non-repetitive peak reverse current of 300 A (tp = 100 μs). The junction temperature range extends from -55 °C to +150 °C.

Feature Summary

• Dual common-anode configuration within an ultra-small flat plastic SMD package
• Approximately 5% Zener voltage tolerance across the E24 series range
• High surge capability with non-repetitive peak reverse power dissipation up to 40 W

Applications

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

Selection Notes

Select this component for designs requiring dual voltage references or protection channels in minimal board space. Ensure thermal management accounts for the 425 mW total dissipation limit under load. Verify that the 5.1 V nominal breakdown aligns with circuit requirements, noting the negative temperature coefficient below 5.6 V.

Part Context

This part belongs to the BZB984 series of low-power voltage regulator double diodes. The series offers various nominal voltages from 2.4 V to 15 V in the SOT663 package. Unlike automotive-qualified variants, this specific product data sheet indicates non-automotive qualification status as of revision 3.

Replacement Considerations

Direct pin-compatible substitutes within the same series include BZB984-C4V7,115 and BZB984-C5V6,115. Cross-series replacements require verification of package dimensions and electrical parameters against the original design constraints.
