In the absolute maximum ratings, the reverse peak voltage should be
400V or higher, the average rectifying current should be 1A or higher,
and the peak surge current should be 40A or higher.
(Full-wave rectifier can be used in out part.)
D1: Rectifier diode
10Ω∼22Ω 1/4W
Reduce the noise terminal voltage.The constant value should be evaluated
in set.
R1: For noise terminal

Varistor must be used. It protects this part from lightning surge and static
electricity.
ZNR: Varistor
For acutual usage, Please kindly evaluate and confirm our part mounted in your product,
Especially, Please make sure to confirm whether the load current exceed Max. rated current
by using the current probe.
