.The BC847AW-QX is a 45 V, 100 mA NPN general-purpose transistor manufactured by Nexperia. It is part of the BC847xW-Q series, which is a series of bipolar transistors with a wide range of current-handling capabilities. This transistor can be used for switching, signal buffering, and amplifier circuits. It is designed to be mounted in a SOT-23 package, which is surface mountable. Its features include a low collector-emitter saturation voltage, high transition frequency, and fast switching time. Other features may include ESD protection, and EMC immunity, as well as low power consumption and operation at low voltages.
