Rectifier Diode Selection: Schottky, Fast Recovery and Standard Compared
A rectifier diode is an easy part to choose from habit. The 1N4007 is in the parts bin, it is rated 1000 V and 1 A, and it goes into the design. Put that same diode in the freewheel position of a 100 kHz buck converter and the converter runs hot and radiates. Forward drop is the number everyone quotes, and it is rarely the one that decides.
