Sometimes this process of identifying unknown SMD components can be speed up if additional details about the equipment that is provided by the user or the user can attach pictures of the PCB, in order to help revealing circuit functionality…

With TS topmark can only be NEC, and 78 can be some subvariant, voltage,.... :

NEC 2SC5437EB NPN Silicon Transistor



Sometimes factory marks smd parts very bad, something like S for 5 and sometimes uses f like t or T like f, 2 like mirrored 5, ....
I see S mirrored on some parts and other letters are ok,.... 8 marked as B, and such things.

Thanks.
