The BAV199-AQ is a 1.4A, 85V general-purpose small signal diode manufactured by Diotec, designed in a SOT-23 package. It is a three-pin device with quick switching action, low forward voltage drop and very low leakage current. It is suitable for general-purpose switching applications, such as protecting against surge voltages or rectifying higher voltages. It is also used to replace other standard diodes, like 1N400x, 1N4148, 1N914 and 1N58xx series. It features low capacitance, fast reverse recovery, and high-temperature operation, withstanding up to 150°C junction temperature.
