High-voltage rectification presents unique challenges to the designer. Careful examination
of the application requirements must be made to choose the proper solution for size, cost
and reliability. Diode parameters are interdependent and require a completely different
thought process when considering high-voltage diodes than when choosing their low-voltage
Stray parameters become major influences with voltage, diodes become more temperature-
dependent and mismatches become more significant. Because of these factors, deep-
diffused multi-junction diodes offer solutions to many high-voltage rectification problems.
