MSAD120-12 Application Field and Working Principle

MSAD120-12 is a kind of rectifier and diode array, which refers to an integrated circuit (IC) device with multiple independent diodes or transistors connected together in various groups. It is mainly used in high voltage circuits and high current power applications. This article will discuss the application field and working principle of MSAD120-12.

Application Field of MSAD120-12

MSAD120-12 rectifier and diode array is mainly used in high-voltage power supplies and circuits, such as computer power supplies, DC-DC converters, AWG, capacitor splitting circuits and other applications with high-voltage power output. It can provide fast switching and excellent electrical performance. It also has additional features like overcurrent protection, Under Voltage Lockout (UVLO), integrated soft start, over temperature protection, inrush current limiting, etc.

In addition, the MSAD120-12 rectifier and diode array has a wide applied range, including universal input ranges from 9V to 32V, as well as output voltage from 0.375V to 11V, with a wide current range from 1A to 12A. It is also suitable for low frequency (<4MHz) DC to DC conversion applications, such as operation amplifiers, MOSFETs and LEDs.

Working Principle of MSAD120-12

The working principle of MSAD120-12 is based on the electrical characteristics of diodes and their use in reverse bias mode. The MSAD120-12 is composed of six independent diodes or transistors connected together, forming an array. A reverse bias is applied across each diode and when the applied voltage exceeds a particular threshold, each diode turns on, allowing current to pass through the diode, blocking any higher voltages from passing.

The current flows through each of the diodes in a single direction and each diode has its own voltage drop, which creates a voltage gradient between the anode and the cathode. This is what creates the “rectifying” effect. The overall output of the MSAD120-12 is the combination of the voltage drops across the individual diodes.

The MSAD120-12 rectifier and diode array also provides additional features, such as overcurrent and overvoltage protection, UVLO, and thermal protection. The overcurrent and overvoltage protection ensure that the device can withstand higher than normal currents without damaging itself. The UVLO feature prevents the device from operating with insufficient input and output voltages, while the thermal protection prevents the device from overheating due to excessive current.

In summary, the MSAD120-12 rectifier and diode array is an ideal choice for high voltage and high current power applications due to its fast switching and excellent electrical performance, as well as its additional features. It has a wide applied range, with input and output voltages ranging from 9V to 32V and 0.375V to 11V, respectively, and current ranges from 1A to 12A. Although the working principle of MSAD120-12 is based on reverse bias mode, it also provides additional features such as overcurrent protection, UVLO, integrated soft start, and over temperature protection.
