2n3904 vs mosfet
When doing any manner of low voltage switching in the past, I've relied on either the 2n3904 or the 2n3906, both 250mA-max devices. However, I'd like to find similar "ye ole trusty" MOSFETs to add to my toolbox, so I figured I'd ask about it here. I'm lookng for enhancement-type, as I want the devices to be normally off.
The 2n3904 and 2n3906 are very common complementary devices, readily available. Likewise, I have SPICE models for each, but with regards to similar MOSFETs, I have zip.
What would you recommend as MOSFET substitutes for the 2n3904 and the 2n3906?
...also, with an NPN or PNP, you can't make a voltage controlled resistor, at least not a linear one nor one that swings above and below ground. That's all about an FET, a MOSFET.
