The 301CNQ035 is part of the rectifier arrays family, called "dual common cathode ultrafast low-loss diodes". It is employed in several industrial and electronics derived applications, particularly in power management, UPS systems and motor drives, among others. This article will cover the application field and working principle of the 301CNQ035.

The 301CNQ035 is a dual common cathode ultrafast low-loss diode with two pins for connection and its anode terminal numbers alternating between two pins. It is specifically designed for applications operating in a wide continuous temperature range from -65°C to 175°C and a high current switching capacity. Typically it has a symmetrical thermal resistance from junction to ambient of 3.2K/W, which makes it a great choice for thermal application. It also has a low forward voltage drop of 1.5V and a reverse recovery time of 20ns. This diode features low-loss silicon die, which make it ideal for high frequency applications, as it improves current conduction and electromagnetic interference performance.

One of its key applications is power management in switches, UPS systems and rectifying circuits. This diode allows for current control when the system requires power, like switching from UPS to mains power. Being able to control high current switching makes this diode perfect for power management. Additionally, it is also used in AC to DC converters in applications operating at frequencies of between 4kHz and 8kHz. Its high temperature operating range and fast switching speed make it perfect for controlling the current flow in such systems.

The diode also finds applications in the automotive sector, where it is mainly used in motor drives. Its high frequency capability and fast switching time make it perfect for automotive applications, where it is used to control the current flow to a motor, reaching speeds of up to 3MHz without introducing any noise or loss. The low forward voltage drop makes it also suitable for switching in automotive applications.

Finally, it is also used in communications applications, especially in circuits that have an extended dynamic range. The low-loss silicon die employed in 301CNQ035 make it suitable for these high dynamic circuits, where higher frequency and fast switching time are required.

The working principle of the 301CNQ035 is based on the core principles of diodes, which is to allow current flow in one direction only, blocking any current flowing in the opposite direction. This diode has two pins for connection and its anode terminal numbers are alternating between two pins, which allows for the current to flow in one direction only. Its fast switching speeds, low forward voltage drop and high current capacity make it suitable for a wide range of applications, from power management to communications.

In summary, the 301CNQ035 is a dual common cathode ultrafast low-loss diode which is employed in a wide range of industrial and electronics applications, including power management, UPS systems and motor drives, among others. Its key features are its low forward voltage drop, fast switching time and wide continuous temperature range. Through understanding the application field and working principles of the 301CNQ035, it is easy to see why it is a popular choice for such applications.
