I imagine every electrical engineer has their own list of "comfortable" parts that they use all the time
ours are like... TIP122, IRF540, (2N/MMBT)(3904/3906/2222), UJ3N120065K3S (look, SiC high-voltage JFETs are useful things, i don't care how weird or moderately-expensive they are), IXD_614, 5-1634503-1, stackpole RNF series resistors, probably a few others that don't come to mind immediately

we actually don't have any diodes on the list at the moment because the real common ones like the 1n4148 or 1n400x aren't remotely suitable for the kinds of work we do and what we would need them for

if you do any EE work, even just as a hobby, I'd like to know what yours are!

@Felthry integrated li-ion chargers and boost/buck drivers but as like, a class of component.
5mm WS2812 5mm LED.
The idea of using external microUSB as power supply, maybe.
@starkatt Huh, I suppose those switching regulator chips are pretty similar in operation, at least if you get the good ones with LT part numbers (TI's ones might be too, never used them though)
we don't have any real experience with li-ion stuff though, or those particular LEDs--when we need LEDs, we tend to use whatever's cheapest in the right color from a reasonably good manufacturer (Kingbright, usually)
