WebBipolar junction transistors or BJT is a semiconductor device which is structured like two p-n junction diodes connected back to back. The three leads of a BJT are Collector, base and emitter. Two types of BJT are NPN and PNP. A Bipolar Junction transistor is a current controlled device. WebThere is no "diode current" in a BJT, only the base, collector, and emitter currents, which can be modeled in different ways. Let's look at the construction of a BJT first, to provide some … WebA diode is a device with two conductors. If you break emitter conductor of a bipolar transistor, then you’ll obtain a “collector–base diode”, but lose a transistor.

WebThe emitter efficiency is known as α = I C /I E. Types of BJT Bipolar junction transistors are available as PNP as well as NPN devices. We present a comparison of these two in Figure below. The difference is the polarity of the base emitter diode junctions, as signified by the direction of the schematic symbol emitter arrow. Webare similar to the junctions we saw in the diodes and thus they may be forward biased or reverse biased. By relating these junctions to a diode model the pnp BJT may be modeled as shown on Figure 2. The three terminals of the BJT are called the Base (B), the Collector (C) and the Emitter (E).

WebUniversity of Connecticut 60 Diode-Transistor Logic (DTL) n If all inputs are high, the transistor saturates and V OUT goes low. n If any input goes low, the base current is diverted out through the input diode. The transistor cuts off and V OUT goes high. n This is a NAND gate. n The gate works marginally because V D = V BEA = 0.7V. Improved gate with … WebzA BJT is physically just two back to back PN diodes, with three contacts, but the current between the emitter and the collector is a minority carrier current in the base. zEssentially, a forward biased diode is used to create a minority current, most of which then goes all the way across to the depletion region of another, reverse biased diode.
