second diode bias given backwards, then only a very small current, if not downright not happen currents, through both dioa.<\/span> <span class=\"notranslate\"> Both this bias, does not produce enough characteristics interesting to discuss.<\/span> <span class=\"notranslate\"> The discussion will begin exciting, if diberiprategangan emitter diodes and diode forward bias current collector is given backwards (so-called bias Forward-Backward), as tampat in Figure below.<\/span><br \/>\n<a href=\"https:\/\/www.tneutron.net\/elektro\/wp-content\/uploads\/sites\/2\/2017\/03\/image-4.png\"><img

biased emitter given by V <sub>BE<\/sub> and diode bias current collector is given back by V <sub>CB.<\/sub><\/span><\/p>\n<p><span class=\"notranslate\"> Due to differences in the concentration of doping in the emitter and base regions, the electrons from the VBE diijeksikan (emitted) from the emitter to the base, resulting in emitter currents, IE.<\/span> <span class=\"notranslate\"> Then, since the base area didop with very little concentration and have a structure that is very thin, only very few electrons that fall into the area that produces the flow Base Base, IB, so that most of the electrons is passed continuously to the collector region.<\/span><\/p>\n<p><span class=\"notranslate\"> Collectors will collect (collected) electrons toward him, and moved him to a voltage V

(Common Base).<\/span> <span class=\"notranslate\"> The magnitudes of the resulting current, IE, IB and IC, can be illustrated in the Figure below.<\/span> <span class=\"notranslate\"> However, this
