ich allerdings den IRF9540N gegen einen IRF4905, schaltet dieser nicht mehr vernünftig aus. Ich "nehme" an das liegt am zu hohen / niedrigen Widerstand R5?! Durch kleinere Widerstände im Bereich ~500ohm funktioniert das wieder. Ist meine Vermutung richtig und wie kann ich diesen Widerstand optimal zum IRF4905 wählen? Wie wird dieser berechnet?
