Darlington array (ULN2003) to N-Channel MOSFET (RFP30N06LE)

One of the reasons I was concerned, I saw some guy had a problem where the MOSFET never would turn fully off.

By "10k input gate-to-sorce pulldown" do you mean a 10k resistor from the MOSFET gate pin to MOSFET source pin? I think I saw a drawing where there was a 10k resistor from get to ground, is that wrong?

Why would 220 ohm resistor protect the mosfet? From voltage spikes? Will the MOSFET fully saturate/turn on if I use this resistor?

Thanks for the replies :slight_smile:
