This is a bit off-topic - but - I am reverse engineering a circuit board so 
that I can make a new PCB with some changes. There are two surface mounted 
transistors in SOT23 configuration. One that is marked "t04" and using a 
multimeter, it tests out as an NPN transistor and I found some documentation 
that states that a "t04" is a PMBS3904 which is equivalent to a 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. Does anyone have any info on this transistor???

It may be M0N (M zero N) also. I do not have catalog book here at home, but 
remember that come european MOSFET transitors have marking starting with "M". 
Especially dual gate ones (BF9xx) but they have 4 pins (SOT143).
The last character may be  the identifier of manufacturer. NXP (Philips) often 
adds "p"
