The S9014 is a NPN transistor in a Surface-Mounted Technology (SOT-23) package, produced by Jinyu Electronics Co. Ltd. It is RoHS-compliant and is designed to provide amplified current gain, excellent collector-emitter saturation, and improved on-off switching capability. It is commonly used as a low-power amplifier in various electrical and electronic systems, such as audio amplifiers, radio-controlled switchboxes, and clock radios. With its low collector-emitter saturation voltage, the S9014 can achieve excellent linearity and reduced power consumption.
