Hi Friends! Hope you’re well today. I welcome you on board. Happy to see you around. In this post today. I’ll detail the Introduction to SR560.
The SR560 is a Schottky diode mainly employed in extremely fast switching applications. High surge current capability device, SR560 is highly efficient and reliable and comes with a maximum recurrent peak reverse voltage of 60V while the maximum RMS voltage is 42V.
Read this post all the way through, as I’ll discuss the Introduction to SR560 covering datasheet, pinout, features, and applications.
Let’s get started.
Introduction to SR560
- The SR560 is a Schottky diode mainly employed in extremely fast switching purposes.
- It is also called a hot-carrier diode that comes with low forward drop voltage.
- It is available in the DO-201AD package with a maximum DC blocking voltage of 60V. The storage temperature range is -55 to 150 C while the average maximum forward current is 5A.
- The SR560 carries two terminals called anode and cathode.
- Low power loss and low-cost device, SR560 carries a low forward voltage drop. It weighs only 1.1g and the colored band on the device indicates the cathode terminal while the other end is the anode terminal.
- Schottky diode is also called a hot-carrier diode. This diode exhibits low electronic energy in an unbiased condition. A barrier is formed due to this low energy that restricts the electron movement. Since a barrier is constructed, a reason this device is also called a hot carrier diode.
- Both Schottky diode and common diode are the same when it comes to the flow of current i.e. both favor the current flow in one direction and restrict it in opposite direction.
- These diodes are different in terms of the voltage needed to power up these diodes.
- Both diodes require 2V DC source voltage where the Schottky diode needs only 0.3V, leaving behind 1.7V to power up the diode. And common diode requires only 0.7V, leaving behind 1.3V to power up the diode.
Before applying this component to your electrical project, it’s wise to get a hold of the datasheet of the component that details the main characteristics of the device. You can download the datasheet of SR560 by clicking the link below.
The following figure shows the pinout diagram of SR560.
- This high efficient component is a two-pin device. Pins are also called terminals used for the external connection with the electrical circuit.
- One terminal is called anode while the other is called the cathode. The anode pin is positive and is the place where the current enters the device while the cathode pin is negative and is the area from where the current leaves the diode.
- It is important to note that the current flows from the anode terminal to the cathode terminal.
- Moreover, this is a unidirectional device that means current flows in one direction only i.e. from anode to cathode.
- You cannot force this device to conduct in both directions. Doing so will damage the component.

SR560 Schottky Diode Construction
When metal is combined with the semiconductor material, they produce Schottky diode. When metals like platinum, tungsten, chromium, and molybdenum are combined with the n-type material they constitute Schottky diode.
The Schottky diode forward drop voltage is dependent on the nature of metal and semiconductor material employed in the formation of this diode.
Schottky diode is a two-pin device where one pin is called an anode and the other pin is called a cathode. The anode pin is positive and is composed of metal while the cathode pin is negative and is made of n-type semiconductor material.
You can also apply p-type semiconductor material for the making of Schottky diode, but they carry low forward drop voltage compared to the n-type material.
- Employed in high-frequency and low voltage inverters.
- Used in polarity protection and DC/DC converters applications.
- Used in freewheeling and logic circuits.
- Used in sample-and-hold circuits.
- Used in solar systems and radio frequency applications.
- Incorporated for signal detection and extremely fast switching applications.
- Used to control the electronic charge.
