D1: Rectifier diode
In the absolute maximum ratings, the reverse peak voltage should be
400V or higher, the average rectifying current should be 0.5A or higher,
and the peak surge current should be 20A or higher.
(Full-wave rectifier can be used in our part.)
10Ω to 22Ω 1/4W
R1: For noise terminal
voltage reduction
Reduce the noise terminal voltage.The constant value should be evaluated
in set.
Varistor must be used. It protects this part from lighting surge and static
electricity.
