The first commercial SiC Schottky diodes were introduced more than ten years ago. Since that date, these devices have been incorporated into many power supply systems. The diodes were upgraded to SiC power switches such as Jfet, Bjt and Mosfet. SiC switches with a breakdown voltage of …
WebFor silicon diodes, the typical forward voltage is 0.7 volts, nominal. For germanium diodes, the forward voltage is only 0.3 volts. The chemical constituency of the P-N junction comprising the diode accounts for its nominal forward voltage figure, which is why silicon and germanium diodes have such different forward voltages. Forward voltage ...
