The S9014 is a NPN bipolar junction transistor manufactured by FuxinSemi. It is a SOT-23 package and RoHS compliant. The S9014 features a high voltage capability of up to 40 volts, a low collector-emitter saturation voltage of 0.8V, and excellent gain linearity. It has a minimum gain of 200 at 10mA current, and a high transfer ratio of up to 80mV/mAdc. The S9014 is suitable for a variety of general-purpose switching and amplification applications, including audio circuit, Darlington circuit, analog multiplexing applications, and operational amplifier. It has maximum power dissipation of 200mW and low output capacitance. The S9014 is an ideal device for high reliability designs, because of its high breakdown voltage, small size, low cost, and high gain linearity.
