nu stiu daca mesajul de mai sus era pentru mine :rade: dar am masurat rezistenta componentei mele si am aflat o valoare de 3.5M intr-un sens si 1.5M in celalalt sens . Presupunand ca ar fi vorba despre o dioda am verificat pe multimetru si caderea de tensiune si am gasit 0.7V . problema ar fi ca am incercat-o intr-un circuit simplu (baterie 9V, led si rezistenta) si conduce in ambele sensuri ; sa fie vorba despre o dioda zener sau este pur si simplu o componenta defecta ?
