WebJan 2, 2024 · The construction and terminal voltages for a bipolar NPN transistor are shown above. The voltage between the Base and Emitter ( V BE), is positive at the Base and negative at the Emitter because for an NPN transistor, the Base terminal is always positive with respect to the Emitter.The Collector supply voltage must also be more … WebMay 22, 2024 · 4.2.3: The PNP Bipolar Junction Transistor. The PNP version of the BJT is created by swapping the material for each layer. The outcome is the logical inverse of the NPN regarding current directions and voltage polarities. That is, conventional current flows into the emitter, and out of the collector and base (echoing the electron flow of the NPN).
