D1: Flywheel diode
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)
D2: Rectifier diode
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.
ZNR: Varistor
A varistor is required to protect against lightning surges and static electricity.
