D2: Rectifier diode
Use a rectifying diode with the peak reverse voltage of 800V or higher,
the average rectification current of 1A or large and the peak surge current of
20A or large.When using an input capacitor of a large capacity , choose a
component that endures the inrush current on power-up.
This product is compatible with full-wave rectification.
