The FMEN-220A family of rectifier diodes is a popular selection for a wide range of electrical applications. It is a single-phase, full-wave, parallel-amplitude, non-saturating rectifier diode array that works on AC power. It is available in several configurations and has a maximum on-state voltage rating of 1.2 kV and a current peak of 220 A.

The FMEN-220A rectifier diode array is ideal for a variety of direct / alternating current (DC / AC) applications, including switching power supply, high-speed rectification, polarity protection for inverters, and high-temperature welding. Due to its high-speed switching ability, compact size, and low noise operation, its suitable for a wide range of power applications where speed, size, and noise reduction are important.

The FMEN-220A diode array is designed for parallel amplitude operation, which makes it suitable for variable speed motor drives, three-phase AC variable speed drives, and many other AC power applications. It is also suited for dc-dc converters and inverters. Its low forward voltage (VF) ensures protection against excessive current, while its low reverse turn-on voltage (VTR) helps to reduce switching losses. Its high current carrying capacity (I MAX) makes it an ideal choice for high power applications.

The working principle of the FMEN-220A diode array is based on a simple physical principle: when a conducting material, such as a diode, is exposed to an electric field, electrons in the material become accelerated and move towards the electrode or terminal with the highest electric potential. When the electrons reach the electrode, they create a current flow. This current flow creates a voltage drop across the diode, which is called the forward voltage (VF).

The FMEN-220A rectifier diode array features a low forward voltage (VF) and a reverse turn-on voltage (VTR), which are important characteristics for reducing power loss in the diode array. The low forward voltage (VF) helps reduce electro-motive force (EMF) loss, while the reverse turn-on voltage (VTR) helps reduce diode turn-on loss. Additionally, the low forward voltage (VF) ensures constant voltage regulation and protection against voltage spikes, while its low reverse turn-on voltage (VTR) ensures stability and extended service life.

The FMEN-220A rectifier diode array is usually connected in series with the load to form a full-wave rectifier. This combination enables the diode to control the current flow direction for both positive and negative cycles of AC power, preventing the load from receiving excessive voltage. The diode also helps to limit the voltage applied to the load. In addition, the diode array’s multiple diodes help to share the applied voltage, reducing its peak while ensuring a consistent current flow.

The FMEN-220A diode array is a valuable component for protecting circuits and preventing excessive current in applications requiring high-speed switching. Its ability to provide a low forward voltage (VF) and low reverse turn-on voltage (VTR) helps to reduce power losses, while its high current carrying capacity (I MAX) ensures efficient power conversion. Additionally, the FMEN-220A diode array’s multiple diodes help to share the applied voltage and current, providing stability and improved service life.
