I am trying to Reverse Engineering A PCB but I have problem to identify some PCB components(Highlighted components). I don't know whether these are transistors or FETs. As without knowing their actual model number i will not be able to identify their pin configurations.enter image description here

    \$\begingroup\$ Those are SMD codes on the components, it isn't always possible to find what the actual component is. You can make a more educated guess by: 1) using a multimeter in diode mode to check for diode junctions in the transistors. 2) Examine the circuit around the transistor to see if it matches a commonly used circuit for a BJT or MOSFET. \$\endgroup\$ Oct 28, 2020 at 8:08

The parts in the top photo are likely Nexperia PMV45EN2 N-channel MOSFETs.

The parts in the bottom photo are likely Nexperia BC849 BJTs from the 'C' beta bin.
