Gunn diode operates on the Gunn effect which is named after its inventor J.B. Gunn. He discovered the periodic variation of current in a GaAs (gallium arsenide) rod in 1963. The microwave device that operates on the principle of transfer of electrons is called as Gunn diode. This is one of the diodes used as […]
The VI characteristics of IGBT is as shown in Figure. In the forward direction, they are similar to those of bipolar transistors. The only difference here is that the controlling parameter is the gate to source voltage Vgs and the parameter being controlled is the drain current. The working principle of IGBT is based on […]
An Insulated Gate Bipolar Transistor in short IGBT is a three-terminal semiconductor device it is a hybrid of MOSFET and BJT for high efficiency and fast switching. The power BJT has the advantage of low on state power dissipation, but it cannot be switched at faster rates due to longer turn-off time, whereas MOSFETs have […]
The full form of TRIAC is Triode for Alternating Current. Let’s discuss working of Triac with vi characteristics and Applications. A Triac is a bidirectional device it allows current to flow in both the directions. It is also known as a bidirectional triode thyristor or bilateral triode thyristor. In the SCR family, after the SCR, […]
Definition of Active components: “Active components are those who has the ability to control flow of electrons either by using voltage or by using another current.” Voltage-controlled devices are MOSFETs, vacuum tubes, while current-controlled devices are bipolar junction transistors which allow one current to control another. Active components can be of different types like semiconductor […]
You can see Shockley diode symbol it is a four-layer (P-N-P-N) semiconductor device. Like pn junction diode It conducts in forward bias and stops conducting in reverse bias. The main difference between a conventional diode and a Shockley diode is, it starts conducting when the forward voltage crosses its breakdown voltage. It is an active component. It […]
