theking0 Posted October 28 Report Share Posted October 28 Salve, sto cercando di capire che diodo sia questo montato tra gate e source del 10NK60Z. Qualcuno riesce ad aiutarmi ? Grazie in anticipo Link to comment Share on other sites More sharing options...

theking0 Posted October 28 Author Report Share Posted October 28 Buonasera Livio, si, da datasheet i due piedini frontali sono gate-source (1 e 3), il drain e' il pad superiore. Link to comment Share on other sites More sharing options...
theking0 Posted October 28 Author Report Share Posted October 28 (edited) Ho trovato una centralina identica e questa ha il diodo con stampigliato "C24", credo sia un zener da 24V Qualcuno può confermarmi la cosa ?

Potrebbe essere, visto la Vgs max di +-30V, ma il datasheet dice che si può non usare: Quote The built-in back-to-back Zener diodes have specifically been designed to enhance not only the device’s ESD capability, but also to make them safely absorb possible voltage transients that may occasionally be applied from gate to source. In this respect the Zener voltage is appropriate to achieve an efficient and cost-effective intervention to protect the device’s integrity. These integrated Zener diodes thus avoid the usage of external components Ciao, Ale. Link to comment Share on other sites More sharing options...
theking0 Posted October 28 Author Report Share Posted October 28 Grazie, della conferma. Lo monto ugualmente visto che in casa dovrei averne da 1W. Link to comment Share on other sites More sharing options...

È un'ulteriore protezione per la sicurezza del mosfet, però la capacità parassita dello zener rallenterà i fronti di pilotaggio. Link to comment Share on other sites More sharing options...
