SB560 Schottky Diode Datasheet, Pinout, Features & Applications

Introduction to SB560

• The SB560 is a Schottky diode used in extremely fast switching applications. It is also known as a hot-carrier diode.
• When semiconductor material combines with the metal, they generate Schottky diode. This diode is a two-terminal device where these terminals are used for the external connection with the circuit.

• One terminal is known as anode made of metal material while the other terminal is called cathode made of semiconductor material.

• The anode side is positive while the cathode side is negative. And current only flows in one direction. This diode blocks the current in the opposite direction. The current flows from the anode pin to the cathode pin.
• This Schottky diode is also known as a hot-carrier diode. In an unbiased condition, this device possesses low electronic energy that results in the construction of a barrier that restricts the movement of electrons. Due to the formation of this barrier, Schottky diodes are also called hot-carrier diodes.
• Schottky diode and common diode operate in a similar fashion considering the flow of current. Both favor current flow in one direction and restrict the current flow in another direction. These devices are different considering the voltage required to power up these diodes.
• Though both devices require 2V DC source voltage, the Schottky diode needs only 0.3V, leaving behind 1.7V to supply power to the diode. While common diode needs only 0.7V, leaving behind 0.3V to supply power to the diode.

SB560 Schottky Diode Construction

• Schottky diode is formed when the semiconductor material is joined with metals like tungsten, platinum, chromium, and molybdenum.
• When these two materials are joined they constitute a barrier that blocks the movement of electrons.
• Recall, the formation of a barrier is due to the low electronic energy in the unbiased condition.
• Commonly, the n-type semiconductor material is used to form the Schottky diode.
• P-type semiconductor materials are also used for making the Schottky diode but they are not preferred over n-type semiconductor materials because the former comes with low forward drop voltage.
• The anode side of the diode is composed of metal while the cathode side is made of semiconductor material. And current flows from the positive anode side to the negative cathode side.
