Puntile redresoare se pot lega in paralel. Pentru a-si imparti curentul in mod egal trebuie sa aiba aceeasi temperatura, deci sa fie montate pe acelasi radiator. Daca sunt in aer una dintre ele se incalzeste si trage aproape tot curentul.

Una din condiţii e să aibă caracteristici identice sau foarte apropiate, pot diferi la tensiunea suportată, dar nu la curent, altfel cea mai slabă se defectează şi o trage şi pe cealaltă după ea dacă nu sînt protejate individual.
