Optoisolators and Optocoupler sound very similar and they are the same in terms of workings and other features let’s see what are optoisolators and optocoupler. There are some differences due to which they are given different names. Photocoupler is another name of the optocoupler. An optocoupler or photocoupler and an optoisolator are semiconductor devices that […]

L293D Pin Diagram, Working and Interfacing of L293D with Arduino
In this blog, we will discuss about L293D Pin Diagram its working, and its interfacing with Arduino. L293D can drive two DC motors simultaneously, with up to 600mA current in each channel. It receives a control signal from microcontrollers such as Arduino, ESP32 Dev Module, etc. based on these control signals it controls the direction […]
MOSFET VI Characteristics, Symbol and it’s Classification
MOSFET Full Form is Metal Oxide Semiconductor Field Effect Transistor. Here we will be discussing MOSFET VI Characteristics, symbol and its classification. They are broadly classified into two types namely enhancement Type and depletion type MOSFET. In an enhancement type MOSFET channel has to be induced for the device to conduct, which is achieved by […]
VI Characteristics of IGBT and it’s Working Principle
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 […]
IGBT-Insulated Gate Bipolar Transistor its Working and Applications
An insulated-gate bipolar transistor (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 a very high […]
SCR as a Switch, its Advantages, Disadvantages and Applications
The SCR has only two states of operation i.e. it can be either fully ON or completely OFF hence SCR can as a switch. There is no “active” region of operation like a transistor.
