Title: Cheap, small signal, through-hole P-channel MOSFETs?
Post by: profdc9 on June 16, 2018, 07:29:31 PM
I use the 2N7000 N-channel small signal MOSFET for many projects because it is convenient and dirt cheap, often available for as little as $0.05 USD a piece.  However, I have never found a similarly cheap, available P-channel MOSFET.  I have used the BS250 but it costs ten times as much as the 2N7000.   Are there any other P-channel through-hole small signal MOSFETs available that can be obtained at a similar price to the 2N7000?  I think through-hole MOSFETs are difficult to get in general but they do exist.  Otherwise I'll stick to using the 2N2907/2N3906 BJTs for projects, but it would be handy to have a P and N channel MOSFET for complementary pairs.  Another option is just using an inverter like a CD4069 biased into its linear region perhaps?
