Schottky Diode Failure Modes
Shottky diodes leak more than standard diodesyour design uses a 40v type which on the face of it is okthe 40v diode you chose will have a lower foward drop than say a 1oov diode so you would think that things are fine and what is the point of having a diode that has a volt rating higher than the chipif you take a shottky diode and apply a reverse voltage to it thats below its rating from say a lab supply you will see a small reverse leakage current if you externally heat the diode by. Failure in the mtr28515 may be due to something other than burnout in the diode. Schottky Diode Wikipedia Reliability Investigation And Characterization Of Failure Circuits Restraint Soft Elettroamici No failures were observed with either ion including at full rated voltage of 45 v. Schottky diode failure modes . The schottky diode is what is called a majority carrier device. T...
