2N7000 series SMT parts are quite popular but haven't seen them used for "our" circuits much.

Subject: [sdiy] Choosing FETS

with J201's Bf245's and even MPF102's all hitting end of life or obsolete, I am now completely confused about what FET to use instead in future designs.


In OLD designs, I can often find (for a price) remaining stocks, but in new designs I need a good, versatile FET that can be used for various applications (vcos, sample and holds, switches, etc)


Does anyone have any recommendations on specific part numbers that ARE NOT being axed?

Are FETS vanishing altogether or is it just coincidence that the FETS that are disappearing are the ones many SDIY designs use?


thanks !
