There are some MOSFETs on some boards, similar to the picture below, which are so similar to single MOSFETs. In fact they are single High and Low MOSFETs that come in one package.
How can you distinguish a single MOSFET from a Dual MOSFET before removing them from boards?
And in case any of the internal MOSFETs gets shorted, how do you know that part in the Dual MOSFET is shorted through the board?
How is testing this type of MOSFET out of boards?

As you can see in the picture...
