I have a project with LEDs which are switched on/off with MOSFETs. But there is this "off mode" slowly reducing voltage period which takes 12ms to go truly to 0 V. I have this Vishay Intertech SI4477DY-T1-GE3 P-Channel MOSFET. Is it possible to reduce this off period to go down faster? Is this MOSFET too slow to do that? This is my shematic, and the processor is an Arduino Nano.
