WebTransistors come in many different packages (chip carriers) (see images). The two main categories are through-hole (or leaded), and surface-mount, also known as surface mount device . The ball grid array is the latest surface mount package (currently only for large transistor arrays). It has solder "balls" on the underside in place of léads. WebTransistor current in p-n-p transistors There are three types of primary currents flowing in the transistors, namely emitter current (Ie), base current (Ib), and collector current (Ic). The direction of these three currents is shown below: Let's discuss a short description of these currents flowing in a PNP transistor. Emitter current

WebOn the other hand, the base current (I B) and collector current (I C) are flowing outwards the transistor. Conventional current direction in npn transistor. Consider the npn transistor as shown in the below figure. The emitter-base junction (n-p junction) is forward biased and the base-collector junction (p-n junction) is reverse biased. So in a NPN Transistor it is the movement of negative current carriers (electrons) through the Base region that constitutes transistor action, since these mobile electrons provide the link between the Collector and Emitter circuits.
