Između G i S kod mosfeta je oksid, praktično beskonačna otpornost. Smile

Taj IRF540 može kontinualno da izdrži 20-ak ampera, tako da tih 6A neće biti problem i sve i da dođe do proboja, ostaće trajno u kratkom spoju, pa će zvučnici biti sigurni. Jedino ako se raspadne, ali mislim da je izuzetno mala verovatnoća, i trebalo bi da prođe dosta vremena...

FET je mnogo bolji izbor zbog vremena odziva, ovaj FET ima dosta malo Qg (72nC), i rise i fall time mu je izuzetno malo ( <50nS), dok releju treba bar 1mS da se uključi. Što znači da će biti dosta manja verovatnoća da pregori zvučnik (dosta kraće vreme će postojati DC na njemu).
Neka me ispravi neko ako grešim...
