What is the BAV99 used for?

It is primarily used for general-purpose switching applications where fast recovery times and high conductance are required.

What are the key specifications of the BAV99?

Key specs include a 70V reverse voltage, 200mA forward current, 6ns reverse recovery time, and 1.25V forward voltage at 150mA.

What should engineers review before using the BAV99?

Engineers should review the thermal resistance (RθJA = 556 °C/W) and power dissipation limits to ensure the device operates within safe temperature ranges.

What should sourcing teams check before buying BAV99?

Check lifecycle (Active), compliance data, distributor availability, and approved-source coverage. Current sourcing signal: Low; readiness: easy.

What is the pinout of BAV99?

Use the BAV99 datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about BAV99 pinout to locate pins, power rails, and interface signals before layout.
