The MSAD70-12 is a component used in the fields of electrical engineering, engineering and semiconductor applications. It is classed as an asymmetric Dual Schottky Array Diode.

This component is used when rectification needs to be performed on a high-impedance circuit, such as in power supplies and motor control applications. It is also used in audio and video equipment, DC/DC converters, UPS systems, and solar and wind power systems.

The MSAD70-12 consists of two separate diodes packaged together in an asymmetric array. Each diode has its own Schottky metal contact, one going to the anode and the other to the cathode. The Schottky metal contact is designed to provide low voltage thresholds and reduce reverse leakage.

The MSAD70-12 has a total capacitance of 12 pF, with a forward voltage drop of 1.2 V and a reverse voltage of 70 V. This component operates in the temperature range from -55°C to 125°C and is available in an SO-8 package for ease of installation.

The working principle of the MSAD70-12 is based on the principles of semiconductor diodes and rectifiers. A diode is a semiconductor device with two terminals, one negative and the other positive. When a diode is forward biased, that is when the positive terminal is connected to the negative, current will flow. When reverse biased, current will not flow. The voltage at which the diode breaks down and becomes conductive is known as the breakdown or avalanche voltage.

Rectifiers are composed of several diodes, which are connected in series or parallel. Depending on the type of rectifier, it works with either AC or DC current. A rectifier circuit for AC current will convert it to DC current by half-wave rectifying and by full-wave rectifying, while a bridge rectifier will convert AC current to DC current by half-wave and full-wave rectification.

In a typical application, the action of the MSAD70-12 is to act as a rectifier for higher-voltage alternating current. This typically involves a full-wave bridge rectifier. The Schottky diodes will be connected in series, with each diode connected to one end of the alternating current source. During the positive cycle, the diode connected to the positive source conducts and the diode connected to the negative source blocks current flow. During the negative cycle, the situation is reversed and the opposite diode conducts and the other blocks current flow.

The result is an AC signal with a DC output. The output voltage is limited by the breakdown voltage of the diodes and the peak inverse voltage of the rectifier circuit. As the voltage surpasses these levels, the diodes start to conduct and cause further current flow.

The MSAD70-12 is suitable for a wide range of applications and can provide a low voltage threshold and low leakage current. It is easy to install due to its SO-8 packaging and its ability to operate over a wide temperature range makes it a versatile component for a variety of applications.
