MDD310-18N1 diodes are arranged in an array to provide a more efficient and effective alternative to individual diodes. The MDD310-18N1 is a power rectifier offering up to 18A of continuous current rating in the 0.6V up to ~1.53V forward dropout region. This device is a single-phase, dual-bipolar, low-voltage surface-mount package with a high-temperature option for short applications, as well as a low-temperature version for higher temperature applications. The MDD310-18N1 provides a superior forward voltage drop to extend the product lifetime.

Application Field

The main application field of the MDD310-18N1 diode is in automotive, telecom, and industrial power applications such as telecom equipment, small motor controllers, home appliances, uninterruptable power supplies (UPSs), and automotive systems. Due to its superior reverse voltage tolerance, this device is also suitable for voltage line surge protection and lighting ballast switching applications. Furthermore, this device can be used as a replacement for bulky and bulky type rectifiers.

Working Principle

The MDD310-18N1 diode is equipped with an extremely integrated active area including diodes, resistors, and zener diode. It functions as a dynamic switch and allows current flow to the output when the input voltage exceeds the rating of the dynamic switch. When the input voltage is too high, the active area of the MDD310-18N1 can works to limit the current by intercepting the excess current. Then the current flow back up to the input. In this way, the voltage does not exceed the diode rating at the same time. When the voltage is low enough, the current flow starts and the diode reaches the forward conduction state.

In the forward-bias condition, the MDD310-18N1 diode provides high-efficiency rectification, allowing significantly lower power losses than conventional rectifier diodes. The device also features low reverse leakage current and reverse recovery time, ensuring low power losses during operation. Thanks to its low reverse resistance and fast reverse recovery time, the MDD310-18N1 can meet challenging specifications in telecom and automotive systems.

Its superior reverse voltage tolerance also allows it to provide superior protection against transients caused by voltage line surges. Additionally, the active area has tight tolerances that ensure superior quality and extended product life. Thanks to its integrated design with low power losses and superior protection, the MDD310-18N1 is an excellent choice for a wide range of applications.
