The BAV99W is a dual surface mount switching diode manufactured by Diodes Incorporated, housed in the SOT-323 (SC-70) plastic package. It features a reverse voltage rating of 75V and a maximum power dissipation of 200mW. The device exhibits a fast switching speed with a typical reverse recovery time of 4ns and low junction capacitance of 1.5pF. It supports an average forward current of 150mA and operates within a temperature range of -65°C to +150°C.
Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct packaging and compliance status. Confirm that the component meets AEC-Q101 standards if automotive reliability is required. Cross-reference the pinout configuration with the target PCB footprint to prevent installation errors during assembly.
Select this component when space constraints necessitate the small SOT-323 package while requiring high-speed performance. Ensure the application voltage does not exceed the 75V reverse rating. Consider the thermal management requirements given the 200mW power dissipation limit in enclosed environments.
This part belongs to the BAV99 family of high-speed switching diodes produced by Diodes Incorporated. It shares functional similarities with other manufacturers' variants but is distinguished by its specific packaging and electrical tolerances defined in the company's DS30045 documentation. It serves as a standard solution for general-purpose diode switching tasks.
Compatible substitutes include BAV99W from Nexperia and Panjit. Verify pin compatibility and electrical ratings before substitution.
