where can i find the datasheets of "CCS2053F637" and "S8050C921"
It would help me to identify the collector, emittor and basis of these
transistors.
Even if you do not find the datasheets there is a simple way to identify
the connections.
Use a modern multimeter with diode test to identify the two diodes inside
the transistor.
Now you know if it is an npn or pnp, and you know which connection is the
base.
The remaining two connections are identified by using the hfe test for
transistors on the multimeter, try both possibilities and the one that
gives the highest hfe is the right one.
