I'm tired of the anti-3.3V logic arguments. What does commodity even mean?

What does standard even mean in MOSFETs?

That was true in the '80s. It might have been true in the '90s. It wasn't true in the '00s. It's not true now.Quote
It means, many electronic components work only with 5V signals. Especially ones for handling high currents.

The voltage required to switch the MOSFET. That's individual and can be extracted from the data sheet. There are only few which do at 3.3V and even fewer of them can handle 50A and up, which is required to use it for switching the 15A of a heated bed without additional cooling.
