BAV99S,115

Overview

The Nexperia BAV99S,115 is a high-speed switching diode encapsulated in a very small SOT363 (SC-88) plastic surface-mounted package. It features four silicon junctions configured as two series pairs within the six-lead device. The component supports a maximum reverse voltage of 100 V and a non-repetitive peak forward current of 4 A at 1 μs pulse duration. Key electrical characteristics include a maximum reverse recovery time of 4 ns, a maximum diode capacitance of 1.5 pF, and a maximum forward voltage of 1.25 V at 150 mA. The device operates within a temperature range of -65 °C to +150 °C.

Feature Summary

• High switching speed with a maximum reverse recovery time of 4 ns
• Low capacitance of 1.5 pF for minimal signal distortion
• AEC-Q101 qualified for automotive reliability standards
• Very small SMD plastic package for high-density circuit design

Applications

• High-speed switching circuits
• Reverse polarity protection
• General-purpose switching applications

Procurement Notes

Verify the specific ordering suffix matches the required packing method, such as T1 or T2 tape and reel configurations. Confirm compliance with RoHS and REACH regulations during procurement. Ensure the marking code K1* aligns with manufacturing site requirements. Validate that the selected packaging quantity meets production needs without exceeding storage limits.

Selection Notes

Select this component when space constraints require a compact SC-88 footprint while maintaining high-speed performance. The quadruple configuration allows multiple switching functions in a single package. Consider the low leakage current and high reverse voltage rating for robust operation in sensitive signal paths or automotive environments requiring AEC-Q101 qualification.

Part Context

The BAV99S belongs to the Nexperia BAV99 series of high-speed switching diodes. This series includes variants like the BAV99 in SOT23 and BAV99W in SOT323 packages. All members share similar electrical characteristics but differ in pin count and physical dimensions. The BAV99S specifically offers a six-lead configuration for dual series diode arrangements.

Replacement Considerations

Direct substitutes within the same family include BAV99 and BAV99W, though package differences must be accounted for. Verify pin compatibility and thermal resistance values when replacing with other series members. Ensure the alternative part maintains the required AEC-Q101 qualification if used in automotive applications.
