Hi, I would like to control my 5V 400mA using FQP30N06 and arduino nano. What gate resistor should I use? What is the formula to calculate it?
That MOSFET won't work with a nano.
You need to find a MOSFET with a lower Vgs
Find something that specifies a low RDs(on) at a Vgs of 5V or less.
Hi,
maybe the 60NF30L will suit your need better.
Vgs 1.0V to 2.5V and RDS(on) VGS= 4.5V, ID= 30A --> 0.0095 Ω to
0.015Ω.
Good choice
The gate resistor should be large enough so that it won't draw more current than the Max for the nano output pin.
So let's use 30mA. (a little less than the max)
5V/30mA = 166 ohms. The closest standard value is 150
They have Vgs 2-4V, why they shouldn't work?
Thanks
You may want to consider the FQP30N06 and the FQP30N06L are not the same with the latter being a logic level MOSFET. Read the data sheets. Next for a good explanation of choosing a gate resistor give this a read.
That being a real good choice. The links should give you a good overview.
