That such partners, I ask your help to replace a component that is a MOSFET of a source. I looked for the DATASHEET of the component that is the AUK S4804 and I could not find it and it is not very commercial. With what kind of configuration and commercial code I can replace it, I thank you for your collaboration and help, colleagues. I ATTACH YOU THE LOCATION AND THE MOSFET DIAGRAM ARE TWO EQUALS THAT THE SOURCE BRINGS. https://drive.google.com/file/d/0Bx72vQkinG6eWm55LWNMaElmRXM/view PAGE 13
