What 3B is
- BC856B - dtc driver pnp (on 1 of the parts below)
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 3B), or from a different maker. Check the package and what the part does in the circuit before replacing it.
