Bjt symbol.

A Bipolar Junction Transistor (BJT) is a three-terminal device which consists of two pn-junctions formed by sandwiching either p-type or n-type semiconductor material between a pair of opposite type semiconductors. The primary function of BJT is to increase the strength of a weak signal, i.e., it acts as an amplifier.suggest, but the basic idea that the BJT consists of three alternating layers of p- and n-type material is quite sufficient from the standpoint of its external electrical behavior. The figure above also shows schematic symbols used for the pnp and npn transistors. The center terminal is always the base. One of the three leads includes an arrow.Transistor Symbol. A diagrammatic form of n-p-n and p-n-p transistor is exposed. In-circuit is a connection drawn form is used. The arrow symbol defined the emitter current. In the n-p-n connection, we identify electrons flow into the emitter. This means that the conservative current flows out of the emitter as indicated by the outgoing arrow.BJT: the arrow represents the base-emitter junction, which acts as a common diode (remember the 0.7 V drop). So the arrow is like the arrow in the diode symbol. MOSFET: This dates back from the JFET days: in that case there's a gate-channel P-N junction, and the arrow points from the P to N doped silicon.

NPN Transistors are three-terminal, three-layer devices that can function as either amplifiers or electronic switches. In the previous tutorial we saw that the standard Bipolar Transistor or BJT, comes in two basic forms. An NPN ( N egative- P ositive- N egative) configuration and a PNP ( P ositive- N egative- P ositive) configuration.
