hi, I want to learn more about Schottky diodes (did I get the spelling right? ) I've heard them called barrier diodes. I've also heard about fast recovery and normal Schottky. when does a Schottky become fast recovery and when is it normal? how does their function work (like the lm2576 stepdown psu in "wattage in voltage devider" thread? why a Schottky and not any other diode. what other types of diodes perform what function? lost of questions! I'm a student without a school (money) the web is my textbook and allaboutcircuits is my teachers: -)
