30. Buck Converter Schottky Diode

Rohit is designing a 12V to 5V buck converter for an embedded board. 

The converter can supply up to 2A load current. 

He needs a Schottky diode as the catch diode to carry current when the switch turns OFF. 

This diode should have low forward voltage drop for better efficiency and enough current and reverse voltage margin for reliable operation. 

He decides to use an SMD diode in SMB package. 

Help him select a suitable diode from DigiKey. 

Make sure it is suitable for buck converter catch path operation and works reliably in industrial temperatures.
