Bjt symbol
BJTs PNP and NPN schematic symbols. 3D model of a TO-92 package, commonly used for small bipolar transistors. A bipolar junction transistor ( BJT) is a type of transistor that uses both electrons and electron holes as charge carriers. In contrast, a unipolar transistor, such as a field-effect transistor (FET), uses only one kind of charge carrier.In PNP BJT's, the current flows from emitter to collector. Both NPN and PNP transistors are controlled by emitter-base current. BJT Schematic Symbol.For the BJT, on an n-p-n transistor symbol, the arrow will "Not Point iN". On a p-n-p transistor symbol, the arrow "Points iN Proudly". This however does not apply to MOSFET-based transistor symbols as the arrow is typically reversed (i.e. the arrow for the n-p-n points inside). Field-effect transistor (FET)

The goal is to help understand these characteristics but not on the physical level of electrons and holes.PNP BJT: Circuit Level Parameters B E C VCB=0 +-+-IC = FIE = FIB IE IB Current gain F: Current gain of the BJT in the forward active operation is defined as the ratio of the collector and base currents: C F B n aE E dB B p B C F I I D N W N W D I I Typical values of F are between 20-200 and: F: In the forward active operation F is defined asMay 14, 2013 · \$\begingroup\$ This is what I suspected - I don't mind a plethora of MOSFET symbols that are all takes on a similar theme but the Circuit_Lab symbol just seems to be in it's own league - it might be trying to mimic a BJT - the emitter and source (for NPN and N channel) do point the same way (now that I have become semi-accustomed to the symbol). BJT vs FET. A lot of times, FET is compared with the BJT let's have a brief overview of their peculiarities in this section. These are some of the significant differences between the two of them; BJT is a bit noisy than FET. BJT has a higher output impedance than FET. BJT is current controlled meanwhile FET is voltage controlled device.
