There are two surface mounted= transistors in=A0SOT23 configuration. One that is marked "t04" and using a= multimeter, it tests out as an=A0NPN transistor=A0and I found some documen= tation that states that a "t04" is a=A0PMBS3904 which is equivalent to a=A0= 2N3904. However, the markings of the second transistor are a mystery to me = (It is marked "MON") and it does not test out as an NPN or PNP transistor. = I suspect that it may be a MOSFET.
