BAV99_L99Z

Overview

The BAV99_L99Z is a small-signal switching diode manufactured by onsemi, featuring a dual series configuration within a compact SOT-523-3 surface-mount package. It is engineered for high-speed applications with a peak reverse voltage of 85 V and a forward current rating of 75 mA. The device exhibits a fast recovery time of 4 ns and a maximum diode capacitance of 4 pF. Operating across a temperature range from -55 °C to +125 °C, it ensures reliable performance in general-purpose switching circuits while maintaining low leakage current characteristics.

Feature Summary

• Dual series configuration integrated into a single compact surface-mount package
• High-speed switching capability optimized for rapid signal transitions
• Low parasitic capacitance designed to minimize signal distortion

Applications

• General-purpose high-speed switching circuits
• Reverse polarity protection in sensitive electronic systems
• Signal steering logic in data processing units

Procurement Notes

Verify the specific suffix L99Z against official onsemi documentation to confirm exact mechanical dimensions and marking codes. Ensure compatibility with standard SOT-523 footprints during PCB layout. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement specifications.

Selection Notes

Select this component when space constraints require a dual-diode solution in an ultra-small footprint. The SOT-523 package offers a smaller profile compared to traditional SOT-23 variants. Consider the 85 V reverse voltage limit and 75 mA forward current rating to ensure adequate headroom for the target application's electrical requirements.

Part Context

This part belongs to the BAV99 family of high-speed switching diodes produced by onsemi. While sharing functional similarities with other industry-standard BAV99 devices, this specific variant utilizes the SOT-523-3 package. It serves as a modern alternative to larger packages, enabling denser circuit board layouts without compromising switching speed or reliability.

Replacement Considerations

Cross-reference with Nexperia BAV99,215 or onsemi BAV99W for pin-compatible alternatives. Verify that substitute components meet the same 85 V reverse voltage and 4 ns recovery time specifications to maintain circuit integrity.
