Reverse current prevention diode DKA40AA220 (20A/2200V)
■ Compatible with DC1000V string solar power systems Effective in protecting solar panels and preventing output power reduction ■ Adopts an easy-to-wire terminal arrangement ■ By increasing the string voltage, the total number of strings in the system can be reduced, allowing for thinner wiring and shorter wiring lengths ■ New development with dedicated diode chips, achieving high voltage resistance while improving VF and thermal resistance ■ Insulated package containing two units with a withstand voltage of 2200V ■ Low Vf (forward voltage drop) Vf(typ)=0.87V(IF=10A, Tj=25℃)
