12A reverse current prevention diode

Solar power generation backflow prevention 12A 1,000Vdc compatible 100 hours salt spray test passed IP67

It was developed to prevent reverse current caused by voltage differences between solar cell strings. By adopting an aluminum housing, we achieved high heat dissipation and waterproof performance. By removing the reverse current prevention diode from the junction box, we not only reduced the size of the junction box but also lowered its temperature. The aluminum housing enhances heat dissipation when mounted on a metal frame, making it possible to maintain the diode's operating temperature at a low level.

Reverse current prevention diode DKA40AA220

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℃)

High Voltage Resistance Backflow Prevention Diode DKA40BA300

Solar power generation system compatible, DC reverse voltage 3000V withstand (per chip) insulated package.

■ Compatible with DC1500V string solar power generation systems ■ Insulation-type package with a DC reverse voltage withstand of 3000V (per chip) ■ Achieves high voltage resistance while maintaining low loss and high heat dissipation By increasing the voltage of the string, the overall loss of the power generation system is reduced, leading to improved power generation efficiency. Additionally, the number of parallel strings can be reduced, which decreases the length of wiring and the number of circuits in the junction box, resulting in lower installation costs.
