Product Description

High Efficiency Schottky Signal Diode For Polarity Protection Application

 

Schottky Signal Diode Introduction

 

Schottky diodes are named after their inventor, Dr. Schottky, short for Schottky Barrier Diode (abbreviated SBD). SBD is not fabricated by the principle of forming a PN junction by contacting a P-type semiconductor with an N-type semiconductor, but by a metal-semiconductor junction principle formed by metal-to-semiconductor contact. Therefore, SBD is also called a metal-semiconductor (contact) diode or a surface barrier diode, which is a hot carrier diode.

 

Schottky Signal Diode Features:

 

High switching frequency

Low forward voltage drop

High efficiency and low power loss

High volume of current and good capability of surge current

 

Schottky Signal Diode Applications

 

High frequency rectifier of switching mode power supplies

Freewheeling diodes

Polarity protection application

DC-DC converters

 

Schottky Signal Diode Advantage

 

SBD has the advantages of high switching frequency and low forward voltage, but its reverse breakdown voltage is relatively low, mostly not higher than 60V, and the maximum is only about 100V, which limits its application range. For example, in the switching power supply (SMPS) and power factor correction (PFC) circuits, the freewheeling diode of the power switching device, the transformer secondary uses a high-frequency rectifier diode of 100V or more, and the RCD snubber circuit uses a high-speed diode of 600V to 1.2kV. The PFC boost uses a 600V diode, etc., and only uses a fast recovery epitaxial diode (FRED) and an ultra fast recovery diode (UFRD). The reverse recovery time Trr of UFRD is also above 20 ns, which cannot meet the needs of SMPS of 1 MHz to 3 MHz in fields such as space stations. Even with a SMPS with a hard switch of 100 kHz, due to the large conduction loss and switching loss of the UFRD, the case temperature is high, and a large heat sink is required, so that the volume and weight of the SMPS are increased, which is not compatible with miniaturization and thinning. The development trend. Therefore, the development of high-pressure SBD above 100V has always been a research topic and a hot spot of concern. In recent years, SBD has made breakthroughs. High-voltage SBDs of 150V and 200V have been launched. SBDs with more than 1kV made of new materials have also been successfully developed, thus injecting new vitality and vitality into their applications.
