They are pretty cheap too.
Personally I use IRFP250 and IRFP9240.
I can get the IRFP250's for £1-50 and the IRFP9240's for £2-50 and that is one off prices !

i need these transistors(IRFP240/9240) for a clone of the firstwatt F2 amp.
i am not able to find them in mumbai, were the ones you got of good quality?
what project did you use them in?
any idea where one can find them in either mumbai or delhi?
Hi,
i purchased them for CHAN Nmos 200 watts amplifier. thought i have not started making the amp, i got them easily in local mkt. i am pretty sure you will get them in mumbai, just search a little.

hi folks
greetings everyone i had the same problem finding hexfets
to build anthony holtons av 1000 av 800 .in delhi in bhagirath palace
KHANDELWAL ELECTRONICS has every type of mosfet hexfet
st brand and irf 460 irf 240 irf9240 irf 9610 and very cheap
IRF 240 IRF9240 90rupees a pair
for 500 watt legend amplifier instead of irf240 used irf250 30 rupees
each.
thanking you

Re: irfp 240 9240
The P-type device is not available here in Calicut...however the IRFP240 & IRFP250 costs 50/- rs per piece.

'Q-fet" planer stripe DMOS are cheap too. These two have similar Gm and similar Vgs/Id slopes, and this makes them more 'complementary', if the term could be used for vertical type power mosfets. IRF540/9540 are not very 'complementary', one has 3-4 times the transconductance of the other, notice the transfer characteristics are very dis-similar, introducing asymmetrical distortion figures. IRF530/9540 would be a much better choice. IRFP250/9240 are far from 'complementary' as well, but IRFP240/9240 are much closer. The goal is to get the slope of the overall Gm/Id figure to be constant, providing lower distortion. This starts with choosing the right components.
I used IRF640/9540. I bought them for €0,75 ->$1US.

Very cheap, I still need to test the prototype, but sounds ok
