One is laid bare by [WizardTim], as he cross-sections a 20KV high-voltage diode. A conventional low-voltage silicon diode has a forward voltage drop of about 0.7V and a relatively low maximum ...

Next is the derivation of the Schottky diode current. The analysis of diode breakdown at high voltage is included as well, as is the construction of a SPICE model including parasitic elements. In this ...
