You don't need limiting resistors for MOSFETs. Try it without them.
I am trying to control some LED strip lights (12V, 2 AMP) with the arduino and am trying to select the correct MOSFET to handle the load. I thought this one (http://www.vishay.com/docs/91325/sihlz14.pdf) might work but it does not. When connected with all the pull down and limiting resistors, the lights are dim. Then I noticed when I connected the Drain to Source without the gate power was getting through and dimly lighting the lights...I have researched several sites and similar projects but they do not have the same conditions. Any thoughts? Thanks community!
You shouldn't recommend this
they can only take 40mA abs max
so a gate resistor of 150 ohms or so is recommended.
The datasheet seems to lack max load capacitance figures,
but typical values are around 100pF
I mean the max capacitance load for the Arduino !!!!
I've one with 25nF gate capacitance for instance.
If you connect drain to source then you completely bypass the device, and if in that state the LEDs aren't lighting up properly its clearly nothing to do the the MOSFET!
