Schottky Diode Shortcomings
Feb 01, 2018

Schottky diode biggest drawback is its low reverse bias and reverse leakage current is too large, such as the use of silicon and metal Schottky diodes, the highest reverse voltage reverse withstand voltage only To 50V, while the value of the reverse leakage current is positive temperature characteristics, easy to increase with temperature rise rapidly, pay attention to the practical design of its thermal runaway concerns. In order to avoid the above problems, Schottky diode reverse bias will actually use much smaller than its rating. However, Schottky diode technology has also been improved, the reverse bias can be rated up to 200V.
