Is there a correct way to connect a spare, unused FET out of a package of multiple unconnected FETs?
This question was asked before:

But I'm hoping for more of a consensus.
I had been thinking that shorting gate to source, and then tying drain to ground, made sense. But then I couldn't think of any problem with just tying all three to ground.
The linked thread is solid in support of doing something, not leaving the FET unconnected, but there are multiple ideas as to what to do: Connect gate to source by resistor, or tie gate to drain and ground the source. There is no indication that either of these is wrong.
Are any of these ideas the best? Are any of these ideas bad? Are they all simply sufficient, and that's all they need to be?
That thread is the first thing on google when I search "unused fets", so maybe we can do a little better.
