Top-of-the-line, modern technology with 0.003 Ohms Rds, 157 Amps supported. Protected vs unprotected has nothing to do with old or new. And yes, the specs on the 2N7000 suck, but who cares? It gets the job done and is the dirt-cheapest part. Beginners don't need performance, they just need lots of parts to play with, so cheapness probably takes priority. > Also, manufacturers occasionally get sloppy about noting their existence What are you talking about? Any MOSFET with ESD-protection has a Human-body model (HBM) ESD specification. Probably in the realm of 2000V, or +/-1700V, depending on how the protection diode works. TI btw makes a ton of ESD-protected MOSFETs with 4000V ESD and like 50nA of leakage. But they're much costlier, and of course surface-mount only because that's what pros use in practice. (Beginners definitely prefer through hole so that it works on breadboards, which is another reason to use 2N7000).

Also, the circuit model shows the protection diode.
