Hello , I have a mosfet as shown below, there are 3 connections for the source pport and 4 connections for the drain port.
What is the logic in this?
Why not to use one pin for one port?
Should i connect them as shown below in the schematics.
Thanks.

What is the logic in this?

Normally to reduce the thermal resistance to the board copper.

 

Hello , so by shorting all sources together and all drains together I did correctly ?

 

Current carrying capacity.
Each pin is about the size of 32AWG wire. You can’t get 10A, peak 79A, through one pin.
