SIC Schottky diode SCS208AGC is used in 1KW 5G communication power supply PFC circuit to effectively improve the system efficiency

With the rapid increase of power consumption and quantity of 5g base station, the power supply problem is also the biggest problem. In 5G wireless side micro station power supply scheme, the direct power supply scheme is commonly used. The power is in the range of 1kW ~ 3KW. The circuit diagram frame of 5g micro station power supply scheme mainly includes single-phase rectification, PFC, LLC transformation and synchronous rectification.

The application of SIC Schottky diode SCS208AGC in 5G MicroStation 1KW power PFC circuit has the following advantages:

1. The reverse voltage VR is 650V, which can meet the application voltage requirement of rectifying output voltage between 300V and 400V, and reserve two times of margin, which can better deal with high reverse voltage;

2. The continuous forward current if is 8a, which can meet the power demand of 1kW; the total capacitance charge QC is 13nc. Small reverse recovery charge can switch at high speed, reduce switching loss and effectively improve the overall system efficiency of the power supply;

3. Because scs208agc can switch at high speed, the switching frequency of PFC switch tube Q2 / Q4 can be increased, so as to reduce the size and cost of magnetic materials L1 and L2, and reduce the cost for the overall power supply design;

4、 The temperature range of working junction and storage is -55~175 ℃, wide temperature range. It can be well adapted to the closed natural cooling conditions when the power box is installed as an outdoor holding pole or wall mounted installation environment.

5. The TO-220AC package has small package volume and is easy to be arranged in the compact power board position.

肖特基二极管是以其发明人肖特基博士（Schottky）命名的，SBD是肖特基势垒二极管（SchottkyBarrierDiode,缩写成SBD）的简称。SBD不是利用P型半导体与N型半导体接触形成PN结原理制作的，而是利用金属与半导体接触形成的金属－半导体结原理制作的。因此，SBD也称为金属－半导体（接触）二极管或表面势垒二极管，它是一种热载流子二极管。

What is Schottky Barrier Diode?

WEET Schottky diode is named after its inventor, Dr. Schottky. SBD is short for Schottky Barrier Diode. SBD is not made by the principle of PN junction formed by the contact between P-type semiconductor and N-type semiconductor, but by the principle of metal-semiconductor junction formed by the contact between metal and semiconductor. Therefore, SBD, also known as metal-semiconductor (contact) diode or surface barrier diode, is a hot carrier diode.

What is a Schottky Barrier Diode? Defination of a Schottey Barrier Rectifiers

The Schottky diode, named after its inventor, also known as Schottky barrier diode or hot-carrier diode, is a semiconductor diode formed by the junction of a semiconductor with a metal. Schottky barrier diode not only  have many applications in today's high tech electronics scene,but also it is one of the oldest semiconductor devices in existence.

It has a low forward voltage drop, a switching speeds that approach zero time and is an electronics component that is widely used in RF applications as a mixer or detector. Also used in power applications as a rectifier, again because of its low forward voltage drop, it lowers the levels of power loss, compared to ordinary PN junction diodes.

The reverse recovery time of Schottky diodes provides extremely fast recovery characteristics. What little reverse recovery time they exhibit is dictated by their capacitance instead of minority carrier recombination such as in conventional PN junction rectifiers. This offers very little reverse current overshoot when switching the Schottky from a forward conducting mode to a reverse blocking state.

Most stronge Fast Recovery Diode in WEET are SMA Schottky Barrier Rectifier SS12-SS110, SMB Schottky Barrier Rectifier SS32-SS310, SMC Schottky Barrier Rectifier SS52-SS510
