.The BC857BU3HZGT106 is a PNP-type, general purpose bipolar transistor, manufactured by ROHM. It is composed of three pins, an emitter, a collector, and a base. It is capable of withstanding a maximum collector current of -100 mA, a maximum emitter current of -100 mA, and a maximum collector-emitter voltage of -30 V. It is suitable for switching and signal amplification applications in a variety of systems. In addition, this part is 100-V avalanche-rated, has a high hFE gain, and features a complementary PNP type. It also features low leakage current, fast switching speed, and good thermal characteristics.
