It can also act as a passive element like a capacitor, inductor, or resistor. Chopper circuits due to high switching speed Voltage Regulators Current controlled device Microprocessors WebNov 7, 2015 · It can be easily controlled as compared to current-controlled devices (thyristor, BJT) in high voltage and high current applications. It has superior current conduction capability compared with the bipolar transistor. It also has excellent forward and reverse blocking capabilities. The main drawbacks are:
WebWe would like to show you a description here but the site won’t allow us. WebMar 30, 2024 · BJT's are current-driven devices. The current through the two terminals is controlled by a current at the third terminal (base). It is a bipolar device (current conduction by both types of carriers, i.e. majority and minority electrons and holes) It has a low input impedance. NPN:
WebA bipolar junction transistor, shortly termed as BJT is a current controlled device that consists of two PN junction for its function. It is configured in two ways as NPN and PNP. Among the two, NPN transistor is the most preferred for the sake of convenience. The NPN transistor is made by placing a p-type material between two n-type materials. WebJan 1, 2009 · I recently received an email from a reader suggesting a change to the chapter on bipolar junction transistors, citing a comment by Douglas Self on transistor theory: namely that BJT's are actually voltage-controlled devices and not current-controlled. Here is the email in its entirety: Hi Tony,
