BAV99 Brief Description

BAV99  is a Dual in series Switching diode, it has two diodes connected in series inside a small SMD package. The SOT-23 package has thee pins through which you can access the Anode and Cathode of Diode 1 and Diode 2 respectively and the point at which the diodes are connected in series as show in the BAV99 pinout image above. The diode has a forward current of 250mA and can withstand peak reverse voltage upto 100V making it suitable for protection and switching applications.

This type of dual package allows the designer to pack in two Diodes in a small space saving PCB space and cost. And since they are connected in series it can be directly used in applications where a series diode will be required, like in case of protecting the input GPIO pins of a microcontroller.  

Applications

• General purpose Switching
• High Speed Switching
• Reverse Polarity Protection 
• Clipping or Clamping Circuits
• Protection circuits
