Schottky Barrier Diodes

The Schottky diode (named after the German physicist Walter H. Schottky), also known as Schottky barrier diode or hot-carrier diode, is a semiconductor diode formed by the junction of a semiconductor with a metal. It has a low forward voltage drop and a very fast switching action. The cat's-whisker detectors used in the early days of wireless and metal rectifiers used in early power applications can be considered primitive Schottky diodes.

We are a professional enterprise engaged in the manufacture and sale of Schottky Barrier Diodes.

Manufacture Process:


Faster recovery time. The small amount of charge stored within a Schottky diode makes it ideal for high speed switching applications.

Less noise. The Schottky diode will produce less unwanted noise than your typical p-n junction diode.

Better performance.

Ability to regulate and stabilize circuit voltage.

Greater control overflowing current.

Usable in smaller circuits.


Schottky diodes are used in electronics industry for many applications in diode rectifier because of its properties. They are used for voltage clamping applications, to prevent transistor saturation. It is used as Schottky TTL in digital devices as these devices require fast switching. as the performance of digital computers is determined by switching speed of diodes, Schottky diode is an important component for digital computers.

1. What is a Schottky Barrier Diode?

A Schottky barrier diode (SBD) is a device in which a semiconductor and a metal such as molybdenum are bonded instead of a pn junction. In general, semiconductors in which metals are bonded to n-type layers have been commercialized. It is suitable for high-speed switching applications, because of small forward voltage and short reverse recovery time.

2. How does a Schottky Barrier Diode work?

In a Schottky diode, a semiconductor–metal junction is formed between a semiconductor and a metal, thus creating a Schottky barrier. The N-type semiconductor acts as the cathode and the metal side acts as the anode of the diode. This Schottky barrier results in both a low forward voltage drop and very fast switching.

3. Where to use Schottky Barrier Diode?

Schottky diodes are used for the voltage clamping applications and prevention of transistor saturation due to the high current density in the Schottky diode. It’s also been a low forward voltage drop in Schottky diode, it is wasted in less heat, making them an efficient choice for applications that are sensitive and very efficient. Because of the Schottky diode used in stand-alone photovoltaic systems in order to prevent batteries from discharging purpose for the solar panels at night as well as in grid-connected systems, containing multiple strings are connected in parallel connection. Schottky diodes are also used as rectifiers in power supplies.

4. What are the advantage of Schottky Barrier Diode?

One of the primary advantages of using a Schottky diode over a regular diode is their low forward voltage drop. This allows a Schottky diode to consume less voltage than a standard diode, using only 0.3-0.4V across its junctions.

5. How to test a Schottky Diode?

Connect the red positive test lead to the anode of the Schottky diode and the black common test lead to the cathode of the diode. Listen for a “beep” or a “buzz” from the multimeter. If the Schottky diode responds as expected, the multimeter will sound a tone.
