Το καρβίδιο του πυριτίου ξεχωρίζει από τους παραδοσιακούς ημιαγωγούς έχοντας εξαιρετικά ευρύ χάσμα ζώνης. Αυτό σημαίνει ότι απαιτείται πολύ περισσότερη ενέργεια για να μετακινηθούν τα ηλεκτρόνια από τη ζώνη σθένους στη ζώνη αγωγιμότητας- κατά συνέπεια, το καρβίδιο του πυριτίου διαθέτει πολύ χαμηλές απώλειες ισχύος - μια ανεκτίμητη ιδιότητα όταν χρησιμοποιείται για εφαρμογές υψηλής τάσης, όπως οι αντιστροφείς έλξης ηλεκτρικών οχημάτων.
