Fast recovery diode
Please note that both the switching and efficiency characteristics of the module are affected by this diode.
Recommended products: UF4007 (VISHAY)
250
D2: Rectifier diode
Use a rectifying diode with a peak reverse voltage of 1kV 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 endures the is strong
against inrush current during power up. Full-wave rectification can be used.
R1: Noise reduction resistor 10 to 22Ω, 1W
Determine the ideal value through actual testing.
ZNR: Varistor
A varistor is required to protect against lightning surges and static electricity.
