Ce fel de dioda este sau cum o descifrez.

Recommended Posts

Salutre am si eu o dioda de sticla smdportocalie cu o dunga albastra de la un invertor pt panouri solare si nu stiu ce valoare are si nici schrma nu o am. Ma poate ajuta cineva? Asta e dioda. Sanatate si multumesc anticipat.Aceasta este dioda.

Diodele marcate cu o singura banda nu se pot identifica decat daca se cunoaste lotul din care provine. Insa cu ceva sanse se poate analiza circuitul si  modul in care este montata si rolul pe care il indeplineste,ZENER,Comutatie etc.

Succes

Daca e valida, o masurati, si in functie de caderea de tensiune de pe ea, va dati seama ce e-redresoare normala/zenner sau Shottky. Daca nu e valida, puneti o poza cu acel invertor aici.

Modelul invertorului PIP2424HS. Ideea e caci pe net nu gaseac nici o schema ceva. Sunt doua diode de 1w de acest model. Cea arsa este pusa in emitorul IGBT-urilor STGW45HF60WD iar piesa neagra dip8 (de fapt cu lipire directa pe placa) este tot un IGBT drive octocuplor seria AT350V (pe net am gasit-o cu seria ACPL-T350) care este si asta arsa. Daca are cineva vreo schema sau ppate cu vreo vloare ceva va tog. Multumesc anticipat.

Nu mi-au placut niciodata SMD-urile si aliajul de lipit fara plumb.
