What is a lowvf Schottky diode?

Lowvf Schottky diode is a semiconductor device with a lower forward voltage drop than ordinary Schottky diode. It can be understood as an upgraded Schottky diode with better performance and lower voltage drop. Therefore, the lower the voltage drop of the lowvf Schottky diode, the higher the efficiency. Therefore, the lower the voltage drop, the lower the heat generation, and the higher the working efficiency of the lowvf Schottky diode.

The advantage of lowvf Schottky diode is to reduce the ineffective loss of the power supply and improve the conversion efficiency of the power supply. The function of a lowvf Schottky diode is the same as that of a traditional Schottky diode. The difference between the two is the VF value and trench process. Lowvf Schottky diode is a kind of forward conduction device, VF is a kind of DC voltage drop, which is the loss generated during operation, the lower the loss, the better.
 
The structure and characteristics of lowvf Schottky diode make it suitable for high frequency rectification in low voltage and high current output occasions, detection and mixing of very high frequency (such as X band, C band, S band and Ku band), and high speed Clamping in logic circuits. Lowvf Schottky diodes are also commonly used in integrated circuits, such as Schottky diodes. TTL integrated circuits have long been the mainstream of TTL circuits and are widely used in high-speed computers.
 
lowvf Schottky diode's DC voltage drop: Because the Schottky barrier height is lower than the PN junction barrier height, its forward conduction mosfet and forward voltage drop are lower than PN junction diodes (about 0.2V lower). Lowvf Schottky diode has a high operating frequency: Because the storage effect of minority carriers in Schottky diode is very small, its frequency response is only limited by the RC time constant, so it is an ideal device for high-frequency fast switching. Its operating frequency can reach 100 GHz.
 
lowvf Schottky diodes are used as rectifier diodes and small signal detection diodes in microwave communication circuits. It is often used in communication power supplies, inverters, etc. A typical application is in the switching circuit of the bipolar transistor BJT, the lowvf Schottky diode is connected to the BJT clamp circuit, so that the transistor is actually in a very off state when the transistor is on, thereby increasing the switching speed of the transistor . This method is suitable for TTL internal circuits of typical digital integrated circuits, such as 74LS, 74ALS and 74AS.
