ROHM BC857BU3T106 PNP Transistor

The BC857B and BC857BU3 are PNP general-purpose transistors suitable for small signal amplification in audio frequency applications. They feature collector-base breakdown voltage of -50V, collector-emitter voltage of -45V, and emitter-base voltage of 5V. With exemplified power dissipation of 350mW for BC857B, they are packaged in SOT-23 and SOT-323 packages, respectively, supporting a maximum collector current of -100mA. These transistors operate across a junction temperature range of -55°C to 150°C, making them reliable for various electronic circuits requiring high voltage and current handling with stability.
