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 counterparts.

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.
