Gikfun Packing RFP30N06LE 30A 60V N-Channel Mosfet TO-220 ESD Rated for Arduino (Pack of 5pcs) EK1658

Seem to be quality made ....

Very easy to use with an Arduino ~5V digital output to turn anything in a DC circuit below 30A on and off. That includes basically anything you can think of related to small electronics projects. It switches incredibly fast, so you can use it for dimming with PWM as well. The connections can be potentially misleading with this MOSFET. Without reading into the details, you would expect to connect the 'drain' connection in the middle to your ground or your lower potential side of your circuit and the 'source' connection on the right side to your higher potential power source. However, that won't work. The current will just flow through regardless of the value at the gate. So connect the gate to your digital output of your Arduino, the 'source' pin to your ground or lower potential side, and the 'drain' pin to your higher potential side or power source. For instance to power an LED, the connections in series might be ( +5V --> MOSFET drain pin ) and ( MOSFET source pin ---> LED ---> Resistor ---> Ground).

Does not work with 3.3v supplied by Raspberry pi, though "RFP30N06LE" is supposed to. Spent a day trying to figure out why my circuit did not work, until coming here!Do not purchase this if you want to use it with the raspberry pi!

Value for your money.

easy to connect work great . I like using these on my displays I build small house and light them up . this gives me a chance to give an fast sample for show the little houses .
