High Voltage Diode Assemblies
-
High voltage diode assemblies are built by adding diodes in series to yield a higher peak inverse voltage. For example, if each diode is rated for 1200 peak inverse voltage (PIV), then six diodes in series would have a total peak inverse voltage of 7200 PIV. The detailed circuit is shown below.
