N-channel power MOSFET - 30V / 60A

When you need to switch a lot of power, N-channel MOSFETs are best for the job. These FETs can switch over 60A and 30V and are TO-220 packages so they fit nicely into any breadboard or perfboard. Heat sinking is easy with TO-220's, but because of the very low Rds(on) of down to 0.009 ohms (depending on the Vgs - check the datasheet), you can get away with no heatsinking for pretty high loads! The threshold voltage is also very low, less than 2.5V so you can control it directly from a microcontroller running on 2.8V, 3.3V, or 5V logic.
