Transistor dcm cleanup - Githubissues

matyro commented 6 years ago

Currently the description and keywords of Mosfets (and other transistors) has some inconsistencies. A uniform design for the library would be nice.

Here is a list of things that you can find currently in the description [?Added for actual numbers] :

?V Vds Mosfet type ?V Logic Level ?V Vgs ?mOhm Ron ?nC Qg (typ) Footprint

Problems:

Missing values
Flipped order
How should the mosfet type be written? Is N-Channel enough or should manufacture specific extensions like OptiMOS/NexFET/OptiMOS/... be included? Should it be named N-Channel MOSFET, N-Channel FET Transistor, N-Channel power MOSFET? The same question with JFET...
When should the transition from mUnit to Unit be? (I think from 99mUnit to 0.1Unit)

Next point are the Keywords what should be included there?

@matyro could you please make a proposal for both fields?

Thank you!

Drain Current and "Vgs" for P-channel mosfets is also inconsistent. For about half the P-Channel (MOS)Fets these are positive in the descriptions, while for the other half these are negative (which is more common).

For an overview: Eeschema / 'a' , and type: "p-channel" in the search box. See also thread and 2nd screenshot at: https://forum.kicad.info/t/p-channel-mosfet-symbols-and-footprints/18012/8?u=paulvdh
