First question asked Welcome!

Hi,

I'm using FS05MR12A6MA1 SiC MOSFET module

as I can see on datasheet, there are two source pins for low side switch of each legs.

do I have to connect it both to gate driver? or is there any reason of two source pins?

it's confusing cause there's only one source pin on high side switches.

Hi @fishintoilet ,

There are two reason:

  1. Electrical symmetry
  2. Pin G and S pin should be close to each other

The number and placement of pin either source or drain pin will totally depend on the module design. The module design for IGBT and SiC, Gen1 and Gen2 module will be different.

You could choose any one source pin when you are designing your driver board PCB.

Dipti
