I am using a micro-controller to switch a logic level MOSFET (the IRLR3103). The output of the MCU is 3.3V. I have a 1K resistor in series with the gate as well as a 100K pull down resistor as close to the MOSFET gate pin as possible.
For my PCB layout I am focusing on keeping the drain (output) trace as short as possible but this means the gate trace from the MCU is as much as 150mm long in some cases. The gate traces are 0.6mm wide on 2oz/ft2 copper.
Does this layout sound reasonable or should I try another layout with shorter gate traces from the MCU?
Edit: I should add that the purpose of the MOSFET is to provide switching for things like cooling fans so high-frequency switching isn't a consideration.
