What is IRF510 MOSFET?
The IRF510 is a very popular, third-generation N-channel-based power MOSFET with low on-state resistance and fast switching. This MOSFET is available in the TO-220 package, used within electronic circuits like; switching circuits, audio amplifiers & power supplies.

Working
Generally, it is a switching device that works whenever enough gate voltage is applied to it. If the applied gate voltage is not enough, then the current will not flow from the drain to the source terminal thus it will turned OFF. Whenever the gate voltage is enough, the current will supply throughout the drain to the source terminals, thus it will turned ON.

Flyback Driver Circuit with 555 IC and IRF510 MOSFET
Working
This flyback driver circuit works from +12VDC to +15VDC at about 3Amps. It stores energy within the magnetic field of the transformer in one half of a switching cycle, after that it releases to the secondary winding in the other half. So this is an efficient flyback driver circuit that uses a 555 IC to pulse a 2N2222 transistor through a square wave at a set frequency by the capacitor as well as the potentiometers.
After that 2N2222 transistor drives the gate terminal of the MOSFET which delivers the pulse to the 10-turn winding on the flyback. The potentiometers in the circuit can be adjusted to get the longest arc. The MOSFET in this circuit must be heatsinked. If the MOSFET still burns up or is too hot then you can put a 4 ohm or a 5 ohm resistor in between the source terminal of the MOSFET as well as the primary winding on the flyback. Ensure that these resistors have the correct power rating mainly for the voltage & current that they will be holding. Thus, the flyback must be wound by ten turns of 14 to 16-gauge solid wire.
