This was using my LP-100. Just thought someone would like to know this. I believe that the N type has a higher capacitance that is harder to cancel out. |
You didn't say which mosfet "A" or "N" you saw higher power on.
Also the datasheet shows the IRF520N has lower input capacitance than the IRF520A however datasheets are not all created equal.
