Problema MOSFET irfz44

Recommended Posts

Daca gasiti rezistenta constanta indiferent cum puneti testerele aparatului atunci sigur e defect. nu trebuie sa gasesti rezistenta GS sau GD, poate conduce doar intre D si S daca este incarcata capacitatea GS.Uite in topicul acesta ca sa vezi cum se masoara un mosfet fara sa-l pui intr-un circuit:viewtopic.php?f=66&t=110037&p=1004385&hilit=masurare+mosfet#p1004385Sau ca sa fii mai sigur faci un montaj simplu alimentat de la 9-12V, pui Sursa la masa, in drena pui un led+rezistor catre +12V. Cand pui poarta la +12V se aprinde ledul, cand o pui la masa se stinge, poate merge si daca pui degetul pe poarta.
