• GKN71/14 Application Field and Working Principle

GKN71/14 are components of the diodes-rectifiers-single type. They are a set of Fast Recovery Epitaxial Diodes, part of the diode product range of Shindengen, the largest leading supplier of rectifier diodes in Japan. GKN71/14 is generally used in switching applications, and it is particularly useful for PFC pre-regulator application in electronic power control systems.

GKN71/14 has many advantages, such as high-speed switching capability, low power consumption during switching, high noise immunity and low conducting conduction losses. In addition, they are designed with a metal barrier construction to reduce switching noise, as well as a guard ring structure to reduce surface leakage current.

The working principle of GKN71/14 can be understood by the following diagram:



The GKN71/14 diode is based on an N type p-n-p material, which contains built-in positive and negative charges. When a control voltage is applied to the anode of the diode, the negative charges on the anode attract and capture the electrons from the cathode. This creates a potential barrier between the anode and the cathode, preventing current from flowing in the reverse direction. Meanwhile, current starts to flow in the forward direction through the diode and collects the electrons from the cathode. This process is known as "forward bias" and is responsible for the conversion of electrical energy into useful power output.

In normal forward operation, the reverse recovery time of the GKN71/14 is very low, which makes it ideal for switching applications. This low reverse recovery time enables GKN71/14 to switch off quickly, so it does not interfere with the operation of other circuit elements.

The GKN71/14 diode also has a good thermal conduction capability, due to its high thermal conductivity coefficient. This allows the diode to transfer energy away from its critical components, thus improving system reliability and efficiency.

In conclusion, GKN71/14 is a versatile diode that provides reliable power control for many applications. Its fast switching capabilities and low power consumption make it perfect for switching applications, while its low reverse recovery time gives it high noise immunity and ensures system reliability. Its high thermal conductivity coefficient ensures that the diode stays cool and efficient during operation.
