BAV99

Overview

The BAV99 is a dual surface mount switching diode manufactured by Diodes Incorporated. It consists of two silicon planar epitaxial diodes configured in series within a single package. The device features fast switching speed and is designed for general-purpose switching applications. Key electrical parameters include a maximum repetitive peak reverse voltage (Vr) of 75 V and an average rectified forward current (Io) of 0.215 A per diode. The forward voltage (Vf) is typically 1.25 V at 150 mA, with a reverse recovery time (trr) of 4 ns. It operates within a junction temperature range of -65°C to +150°C.

Feature Summary

• Dual configuration containing two series-connected standard switching diodes in one compact package
• Fast switching speed suitable for high-frequency signal processing
• Qualified to AEC-Q101 standards for automotive reliability
• Totally lead-free and fully RoHS compliant construction

Applications

• General purpose switching circuits
• Automotive electronics systems requiring AEC-Q101 qualified components
• Signal demodulation and detection
• Logic level shifting and protection

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pinout compatibility and package type. Ensure the selected variant meets the required reverse voltage and current ratings for the target application. Confirm RoHS compliance status if environmental regulations apply. Check for any recent product change notices that may affect mechanical dimensions or material composition before finalizing procurement.

Selection Notes

Select the BAV99 when a dual-diode solution is required in a small surface-mount footprint. Consider the 75 V reverse voltage rating and 0.215 A current capacity against circuit demands. Evaluate the 4 ns reverse recovery time for suitability in high-speed switching environments. Compare alternative packages such as SOT-23 or SOT-363 based on board space constraints and thermal requirements.

Part Context

The BAV99 belongs to the family of dual surface mount switching diodes produced by Diodes Incorporated. It serves as a standard component for replacing discrete dual-diode arrangements, reducing board space and assembly complexity. The device is widely used in consumer electronics, telecommunications, and automotive applications where reliable fast switching is necessary. It is often cross-referenced with similar parts from other manufacturers offering equivalent electrical characteristics.

Replacement Considerations

BAV99HY is listed as a replacement option with similar pinout and package characteristics. Verify electrical parameter equivalence before substitution.
