The BC856B is a NPN (Negative-Positive-Negative) SOT-23-style RoHS (Restriction of Hazardous Substances) compliant transistor manufactured by AnBon. It is designed for power switching or amplifier applications, and has a low noise figure and good gain linearity. It can be used in applications such as RF amplifiers, switching circuits, and audio amplifiers. The package is small, measuring just 1.9 x 1.25 mm, and is lead-free. It operates within a wide temperature range from -65°C to 150°C. It has a peak forward current rating of 1 A at a collector current of 400 µA and a collector-emitter voltage (VCE) rating of 40 V. Additionally, it has a collector-base voltage (VCB) rating of 60 V, an emitter-base voltage (VEB) rating of 5 V, and a DC current gain (h FE ) rating of 65 to 500.
