1B SMD marking code - BC846B | Circuit Fixers

← All marking codes

Found on 17 components on 8 boards, in SOT23 package.

What 1B is

BC846B - NPN bipolar junction transistor, general-purpose switching and amplification (SOT23 · on 17 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 1B), or from a different maker. Check the package and what the part does in the circuit before replacing it.
