CD1408-FU1200 Application Field and Working Principle

The CD1408-FU1200 is a single-phase high-efficiency metal-oxide-semiconductor (MOS) rectifier diode. It is designed for applications such as pulse rectification and AC/DC power conversion. The device is a MOS structure which can provide the high efficiency and fast switching speeds required for switching power applications. This diode offers low power losses and is suitable for high volume production.

The CD1408-FU1200 has a peak forward blocking voltage of 1200V. It is rated to operate over a junction temperature range of -55°C to +180°C. It is an ideal choice for high current applications with a maximum forward current rating of 32A. The device comes in a standard DO-220 package suitable for surface mounting, saving costs and space on printed circuit boards. The device also features low reverse leakages currents, improved surge handling capability, and improved EMI/RFI noise immunity.

To understand how the CD1408-FU1200 rectifier diode works, it is important to understand the concept of forward and reverse biasing. Forward biasing occurs when an appropriate voltage is applied to the diode, causing current to flow. This is referred to as forward biasing because the majority of positive charge carriers (holes) and the majority of negative charge carriers (electrons) can flow from one pair of electrodes to the other, thus allowing a current to flow through the diode. On the other hand, reverse biasing occurs when a voltage of opposite polarity is applied to the diode, causing the majority of charge carriers to be “blocked” from one pair of electrodes to the other, thus preventing a current from flowing through the diode.

In the simplest terms, a CD1408-FU1200 rectifier diode is designed to regulate the flow of current in one direction. When the voltage applied to the diode is between 0V and 1200V, the diode is said to be forward biased, allowing the majority of positive and negative charge carriers to flow freely from one pair of electrodes to the other, thus allowing current to flow through the diode. When the voltage applied to the diode is greater than 1200V, the diode is said to be reverse biased, blocking the majority of charge carriers from flowing from one pair of electrodes to the other, thus preventing a current from flowing through the diode.

The CD1408-FU1200 rectifier diode is a reliable solution for applications such as power conversion, soft-switching, and pulse rectification. The device is fast switching, efficient, and capable of withstanding high power levels. It is an ideal choice for high-current applications with a peak forward blocking voltage of 1200V and a maximum forward current rating of 32A. The device also features low reverse leakages currents, improved surge handling capability, and improved EMI/RFI noise immunity. The CD1408-FU1200 is a single-phase, high-efficiency rectifier diode suitable for surface mounting, saving cost and space on printed circuit boards.
