Found on 5 components on 1 board, in SOT23 package.
What 5B is
- BC807-25 - PNP small-signal transistor, general purpose amplification (SOT23 · on 5 of the parts below · in our catalogue with this marking)
One code, more than one part. SMD marking codes are short, and manufacturers reuse them: the same code can be a different part in a different package
(a SOT-23 transistor and a SOD-123 diode can both be marked 5B), or from a different maker. Check the package and what the part does in the circuit before replacing it.
