Hello, I've been reading the web page:

https://www.onelectrontech.com/mosf...os-on-resistance-inrush-current-applications/

that covers using MOSFETs as load switches.

I am not an expert with MOSFETs and that is why I'm reading that web page and posting my questions here for help.

On that web page they have:


Here it says that VSG,MAX is from the datasheet. This would be the voltage from Source to Gate.

I am looking at the datasheet for SI7157 and I can't find that spec. Can anyone help me please?

https://www.vishay.com/docs/62860/si7157dp.pdf

They have the spec VGS +/-12V.

Thank you very much

 

That +/- 12V is the maximum VGS, as stated in the datasheet "Absolute Maximum Ratings" as a "Limit" in the column

 

Hello, is that the same as VSG,MAX as indicated in the web page I referenced?

 

Would VSG be -12V?
