Hello Guys,

Just reposting my problem wit the ST1S10
on my PreAmp.
VIN =12V
Soon as I transmit the ST shorts the input.

If Powered bellow 11V works OK.

The specs of the STM states solid protection for over temp, short, etc.

Still trying to figure out why is this hapen.

Already smoked 4 STs.

And YES pad is soldered properly.
