Be sure to use fuse for safety.
Please verify operation and characteristics in the customer's circuit before actual usage.
Ensure that the load current does not exceed the maximum rating.

Above 600V, current : above 2.0A, Fast recovery diode
Please note that both the switching and efficiency characteristics of the module are affected by this diode.
Recommended part : CMF01 (Toshiba)
Use a rectifying diode with a peak reverse voltage of 800V or higher, an average rectification current of 1A or large and a
peak surge current of 20A or large.When using a large capacitance input capacitor, select a component that is strong against
inrush current at power up. Full-wave rectification can be used.
A varistor is required to protect against lightning surges and static electricity.
