Use a rectifying diode with a peak reverse voltage of 400V or higher, an
average rectification current of 1A or larger and a peak surge current of
20A or larger. When using a large capacitance input capacitor, select a
component that is strong against inrush current during power up.
Full-wave rectification can be used.
1.0 to 2.2 ?, 1/4W
Determine the ideal value through actual testing.
A varistor is required to protect against lightning surges and static
electricity.
