Working Principle

The MD1890A-DKM2MM rectifier array features four branches, each consisting of two SBDs and two MOSFETs. The SBDs provide low forward voltage drop and high reverse biased avalanche ratings, while the MOSFETs offer low on-resistance and fast switching speeds. The array is designed to convert AC current into DC current for use in power supplies, dc-dc converters, and other related circuits. When an AC voltage is connected to the rectifier array, the peak AC voltage is transformed into DC voltage with some ripple. The forward voltage drop is relatively low (around 0.6V to 0.7V) which reduces the initial power loss. The reverse biased avalanche ratings ensure that the array can withstand large voltage transients without damage.

Conclusion

The MD1890A-DKM2MM is a robust and reliable rectifier array that is designed for a wide range of applications in power supplies, dc-dc converters, and other related circuits. It features four branches, each consisting of two SBDs and two MOSFETs which provide low forward voltage drop and high reverse biased avalanche ratings. The array is suitable for harsh environment applications due to its high temperature and vibration ratings. Overall, the MD1890A-DKM2MM is an ideal solution for applications requiring reliable and efficient power conversion.
