What is a flyback diode, its structure, principles, functions, types, operational procedures, and development history 3

4. Insulation protection: To avoid external damage or dust pollution to the freewheeling diode, it is recommended to install appropriate insulation protection measures during use, such as a casing or casing cover.diode

5. Precautions: When operating the freewheeling diode, avoid overloading or short circuiting, promptly handle any abnormal situations that may occur in the circuit, and avoid damaging the freewheeling diode

6、 Development history:

A freewheeling diode, also known as a Schottky diode, is a special type of diode with low turn-on voltage and high withstand voltage, commonly used in power circuits and power electronic devices. Its development process can be traced back to the 1920s.

The earliest freewheeling diode was the metal semiconductor contact diode invented by German physicist Wolfgang Schott in 1914. Subsequently, in 1941, scientist M.S. Fowler utilized semiconductor materials to fabricate large-area P-N contact diodes, pioneering the research direction of modern freewheeling diodes.diode
