Hi there. I've recently bought in parts to have a go at making a mosfet myself as i was interested in having a go at building one.

I've built acording to this diagram and fired it up last night for a test.

The thing turns on powers up the motor and i can feel slight active breaking, however it doesnt stop instantly like one i have used before. It kind of spins to a stop a bit quicker than before but still is not instant how it should be.

This is the diagram and the parts i used were these.

IRF4905
IRL1404
P6KE24A = TVS 24V 600Watt
2x 100R's
10uF 25V Cap
1x 220R
1x 4.7k

Any help would be appreciated, many thanks,
