SparkFun MOSFET Power Control Kit
This is the SparkFun MOSFET Power Control Kit, a breakout PTH soldering kit for for the RFP30N06LE N-Channel MOSFET. This kit is extremely simple to assemble with only 10 pins to solder. If you are looking for a little more control over projects that require a little more power than normal but need a better way than your breadboard, this kit is perfect for you
Included in each kit is a SparkFun MOSFET Power Control PCB, two screw terminals (one 2-pin and one 3-pin), a 10k resistor, and a single RFP30N06LE MOSFET. What we really like about this particular MOSFET is that it's very common and offers very low on-resistance with a control (gate) voltage that is compatible with any 3-5V microcontroller or mechanical switch. This allows you to control high-power devices with very low-power control mechanisms.
Note: While the MOSFET is rated to 60V 30A, the circuit board traces are only rated to 3.5A.
Connections
Connect the kit to a controller, like a Raspberry Pi. The drawings is for the Sparkfun kit but can be seen as a universal simple MOSFET hookup guide. This particular MOSFET seems to have some zener diodes integrated and can therefore handle inductive loads too (like a relay or a DC motor).
The circuit use a RFP30N06LE N-Channel MOSFET and a 10 kOhm resistor that acts as a pull-down. Connections with internal marks and traces:
