Hello,
I want to adapt the STGSH50M120D to the circuit I already have working, but I have a question about pins K1 and K2. Will there be any problem with the STGSH50M120D if I don't use K1 and K2, leaving them disconnected?
Welcome
The pins marked K are the so-called Kelvin pins usually used for four-terminal sensing. You do not have to use them, but then you lose the main advantage – the ability to avoid voltage drop at the connection between the pin and the internal silicon. This is not a problem at small currents, but it certainly is at full capacity with the possible pulse of 240A of this module.
Does this answer your question?
Regards
/Peter
