What is the difference between rectifier and Schottky diode?

Schottky diode, also known as barrier diode is mainly used in low voltage circuits because the forward voltage drop of Schottky diode(Vf) is less than a rectifier diode. The forward voltage drop of a Schottky diode is typically in the range of . 25 to 0.5 V whereas the Vf of a rectifier diode is around 0.7 volts.

How does a Schottky rectifier 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.

What is the advantage of Schottky 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.

What is a power Schottky Rectifier?

Schottky rectifiers have been used for over 25 years in the power supply industry. The primary advantages are very low forward voltage drop and switching speeds that approach zero time making them ideal for output stages of switching power supplies.

Why Schottky diode is fast?

Schottky diodes are significantly faster since they are unipolar devices and their speed is only limited by the junction capacitance. The switching time is ~100 ps for the small-signal diodes, and up to tens of nanoseconds for special high-capacity power diodes.

Can a Schottky rectifier be made larger than 200V?

Schottky diodes Presently the breakdown voltage of the Sili- con Schottky diode cannot be reliably made larger than 200V. However, the drawback of the Silicon Schottky rectifier can be ad- dressed by fabricating the devices by using other semiconductor materials, such as gal- lium arsenide and silicon carbide.

Which is the latest generation of Schottky diodes?

Power Schottky diodes are belonging to the STPOWER family. The latest devices are 60 V, 80 V, 120 V medium forward voltage (V F) and reverse leakage current (I R ), new 170 V and 200 V power Schottky diodes.

Are there power Schottky rectifiers for SMB PCB?

In addition, ST’s 40, 60, 100 V and 200V power Schottky rectifiers are now available in the new SMA Flat and SMB Flat packages providing even more power density in 1 mm thick only. They are fully compatible with SMA and SMB PCB footprints and even with SOD128 footprint.
