It is suitable for applications where a combination of high switching frequency, low forward voltage drop, and fast recovery time is required.

Working Principle

The MDD312-22N1 is a four-diode array that operates by a simple process. When the device is connected to a direct current (DC) source, such as a battery or an alternating current (AC) source, such as a wall outlet, the array rectifies the AC input current and transfers it to the storage/load circuit. The MDD312-22N1 uses four synchronous field-effect transistors (FETs) to minimize voltage loss and efficiently switch current between the positive and negative power sources. The MDD312-22N1 consists of a common-cathode and four common-emitter FETs, which simultaneously and rapidly switching current between the positive and negative power sources. As the FETs switch, they limit the current flow to the storage/load circuit, in addition to providing a constant reverse-blocking diode. This ensures that the voltage generated is consistently smooth and eliminates the need for additional protective circuitry, resulting in improved design efficiency.

Conclusion

The MDD312-22N1 is a diode-array rectifier for use in a variety of applications. It is designed to provide a low forward voltage drop and a fast recovery time, while simultaneously offering superior reliability and ruggedness. The array rectifies the AC input current and transfers it to the storage/load circuit while minimizing voltage loss, providing a constant reverse-blocking diode, and eliminating the need for additional protective circuitry.
