The GKN240/14 device is a rectifier diode, a single device used to convert alternating current (AC) to direct current (DC) in electronic circuit applications. In order to better understand its application field and working principle, it’s necessary to review rectifier diode function, its construction, and the various devices used in rectification.
Rectifier Diode Function
Rectifier diodes are the most common devices used in rectification. A rectifier diode is a conducting PN-junction. The positive side of the diode is referred to as the anode, while its negative side is referred to as the cathode. When an AC voltage is applied across such anode/cathode junction, current will flow in one direction but not the other.
By applying the AC voltage to the diode in a certain configuration, only one half of the wave will be allowed to flow through the diode, the remaining portion is blocked. This process is known as half wave rectification. The two major benefits of this process are:
- A DC voltage is created from an AC input.
- A change from a full wave AC to a half wave DC is achieved.
GKN240/14 Function & Application Field
The GKN240/14 is a rectifier diode specifically designed for applications where a higher breakdown voltage and power handling capability is required. The device is ideal for use in power switchmode, motor control, and high current switching applications. It can handle up to 45A continuous forward current, with a peak reverse voltage of 1200V.
In addition, the device’s low leakage characteristics on the reverse side makes it ideal for use in circuits that involve firewalls and other safety applications. This diode also exhibits very fast switching speeds, making it suitable for use in high frequency RF applications. Finally, the device also features a low forward voltage drop, making it an ideal choice for efficient power conversion applications.
Working Principle of Rectifier Diodes
To understand the working principle of rectifier diodes, we first need to understand what happens during forward conduction. A forward conduction event occurs when voltage is applied to the anode side of the diode and current flows in the forward direction (from anode to cathode). This current is limited by the doping profile of the device, with the limitation determined by a region known as the depletion zone. This zone creates a short circuit between the anode and the cathode when the anode is more positive than the cathode, an event known as turn-on.
When voltage is applied to the cathode side of the diode, a reverse conduction event occurs. In this case, current can flow in the reverse direction (from cathode to anode), but it is limited by the device’s doping profile and the load applied to the cathode. After the reverse conduction event, the device will turn off and all current flow ceases.
Conclusion
In conclusion, the GKN240/14 is a rectifier diode specifically designed for higher breakdown voltage and power handling capability. Its various features make it an ideal choice for use in power switchmode, motor control, and high current switching applications. It’s important to understand the working principle of rectifier diodes in order to make the most effective use of them in various applications.
