Oh Yes, The Fet capacitance..
I purposely held off on that ...hehe.
True, Not much inductance in the diode..just the supporting wiring that im worried about as the lengths can start to influence the switching some.
not much..also at my location I have to worry able RFI , I am a 1/4mile from a 100kW AM broadcast facility. As well as my own radiation from my own ham amplifiers.
Good luck finding a suitable TO-220 style..
Ive been hunting for something that was not surface mount for some time now.
If we can find a FET with the same characteristics as the 2sk2504 or the
IRLR3105 in a TO-220 or something we could bolt-down that would make me a happy camper. I dont relish the thought of adding metal to a SMD.
Ive tried the IRFz20, 630, 720, 730, 820 and 830 and didnt like the performance.
Lately Ive been working on a better solution to DIY drivers and replacement DPSS analog drivers.
Yes, The FET saturation is very important. As well as the slew rate of the op-amp.
