Diode: this is a one way electronic device that permits the passage of electric current in one direction. This is analogous to opening a water tap and the water starts flowing. This water can never flow back into that with which it has been released. This simply means that a diode will always block any electric current coming in the reversed direction provided the reversed blocking voltage is not exceeded.
Reverse blocking voltage is the maximum reversed voltage a particular diode can withstand. diodes have different sizes, functions and or applications. They have different electric current and voltage handling capabilities depending on fabrication. Diode as a semiconductor can be connected either in series and in parallel depending on what an individual want to achieve. 2CL2FM are connected in series to increase the voltage handling capacity while they can be connected in parallel to increase their current holding capacities.
The diode structurally is a two terminal device; the anode ( the positive terminal) and the cathode ( the negative terminal). Signal ( current or voltage) from the anode and received at the cathode only in one direction. this is the more reason why the diode find its applications as rectifiers. It can also be used in logic and binary circuits. diode ranges from signal diode to power diode based on the manufacturer’s data sheet.
To see how a diode can be connected in series and parallel, other applications and tricks on diode and other electrical and electronics components will be explored in my next article.
