dioda cuptor microunde t4512h

salutari!am vrut sa verific o dioda t4512h (curent max. 0.45A direct, 12000 V invers) dintr-un cuptor cu microunde.nu se poate verifica cu multimetrul digital pt ca intra in conductie de la 6V in sus, asa ca am legat-o la 12VCC direct si am masurat curentul prin dioda cu ampermetrul la cap de scala 10A.curentul prin ea a ajuns la 2.4A si dioda a inceput sa se incalzeasca puternic, moment in care am realizat ca trebuia sa fi limitat curentul prin dioda cu o rezistenta.intrebarea este : am distrus dioda?multumesc!
