The Difference Between Schottky, Zener And Rectifier Diodes

 

In electric circuits, a diode is a part that permits the flow to stream just one way. Normally, a diode is built by

putting an n-type and a p-type semiconductor in touch.

 

What Is A Schottky Diode?

A Schottky diode is an exceptional diode built utilizing a metal-semiconductor junction rather than an n-p junction utilized in different diodes. Because of this, the voltage drop across a Schottky diode when it is leading a forward current (the cut-in voltage) is little contrasted with ordinary diodes. Note that when the forward voltages are lower, the converse flows are bigger, which is one of the drawbacks of a Schottky diode. When a diode directing a forward current is immediately put under reverse bias or is switched off, it sets aside a limited quantity of effort for the forward current moving through the diode to fade away. The time taken for this is called reverse recovery time. Contrasted with ordinary diodes, the reverse recovery time of Schottky diodes is a lot more modest, making them appropriate to be utilized in quick switching circuits. Schottky diodes are utilized for voltage clamping applications and in circumstances where the proficiency of the circuit should be expanded (since they have a low potential difference across them, they disseminate less power). For example, they are utilized in the development of solar cells. 

                                                                     

What Is A Zener Diode?

It is an uncommon property of the diode rather than any exceptional sort of gear. The individual named Clearance Zener designed this diode property; it is named after him as recognition. The extraordinary property of the diode is that there will be a breakdown in the circuit in case the voltage is applied across a reversed biased circuit. This doesn't permit the current to stream across it. When the voltage across the diode is expanded, temperature likewise increments and the crystal ions vibrate with a more noteworthy amplitude. This large number prompts the breakdown of the depletion layer. The layer at the intersection of  N-type and P-type. At the point when the applied voltage surpasses a particular sum Zener breakdown happens. This is only a solitary diode associated in a reverse-biased mode and the Zener diode can be associated with reverse bias positive in a circuit. We can associate it with various applications.  For comfort, it is utilized regularly. While examining the diode circuits, we should glance through the graphical portrayal of the activity of the Zener diode. It is known as the V-I qualities of an overall P-N intersection diode.

What Is A Rectifier Diode?

A rectifier diode is a semiconductor diode used to rectify AC (alternating current) to DC (direct current) utilizing the rectifier bridge application. The option of rectifier diode through the Schottky boundary is highly esteemed inside computerized gadgets. This diode is skilled to direct the upsides of current, which change from mA to a couple of kA and voltages up to a couple of kV. The planning of rectifier diodes should be possible with Silicon material, and they are equipped for directing high current values. These diodes are not popular but rather still utilized Ge or gallium arsenide-based semiconductor diodes. Ge diodes have less permissible reverse bias voltage than a lesser reasonable junction temperature. The Ge diode has an advantage when contrasted with Si diode with a low limit voltage value while working in a forward bias. The rectifier diode has two gatherings of specialized boundaries like passable cutoff parameters and trademark parameters.
