Marking of electronic components, smd codes 3f, 3f, 3fw. A transistor, also known as a bjt bipolar junction transistor, is a current driven semiconductor device which can be used to control the flow of electric current in which a small amount of current in the base lead controls a larger current between the collector and emitter. The three layers are called the emitter, base and collector. Figure 5 below shows a circuit example which turns on the collectoremitter junction by energizing the base, or biasing the transistor.
