DUR75120W

Diodes - Rectifiers - Single

The DUR75120W is a rectifier diode made using a stud type package for use in single phase, bridge full wave rectification applications. It is designed for medium power rectification applications in power supplies, automotive power systems, and high switching frequency protocols.

Application Field

The high surge current application characteristics of the DUR75120W make it suitable to use in medium power rectification applications in power supplies and automotive power systems. It also has wider across terminals due to its stud type package material. The size of its package is a very convenient size as it can fit easily into a power supply. The fast switching speed of the diode allows for high di/dt control and current feedback during the rectification process.

Working Principle

The working principle of the DUR75120W rectifier diode is based on the same principles as other rectifier diodes. It has a pair of plates, with one being negative and the other positive. A metal oxide semiconductor field effect transistor is located between the plates, which allows for low forward voltage drop and very fast switching. When the positive plate is connected to the positive of the power supply, electrons flow from the negative plate of the diode to the positive plate, causing current to flow. The faster the electrons flow, the higher the output voltage and power.

The switching frequency of the diode can also be adjusted easily, allowing for greater current control during the rectification process. The current that flows through the diode is governed by its forward voltage drop, which is controlled by the gate of the MOSFET. The current then passes through a resistor before reaching the negative plate, creating a voltage drop across the resistor. This voltage drop is then used to control the output voltage of the rectifier.

Conclusion

The DUR75120W rectifier diode is a very effective and efficient device for medium power rectification applications. It has a high surge current characteristics, and its stud package material allows for easier fitting in limited spaces. The internal MOSFET provides high di/dt control and fast switching speeds during the rectification process, and the adjustable switching frequency allows for higher voltage control during the process. All of these characteristics make the DUR75120W ideal for applications in power supplies, automotive power systems, and high switching frequency protocols.
