MDD26-12N1B is a diode array that is used to protect electrical devices from unwanted power surges, reverse polarity input and voltage spikes. Commercial, industrial and automotive applications use this diode array to protect against over-voltage, high-frequency, undershoot and reverse current. The MDD26-12N1B offers protection against reverse polarity, reverse current, and over-voltage. With its superior Vf and high holding voltage, it provides superior performance and reliability.

The application field of MDD26-12N1B diode array is mainly found in small- to medium-powered personal electronic devices, as well as automotive and communication systems. This diode array is widely used in power supplies, mobile phone chargers and adapters, digital audio/video devices, and sensor systems. The MDD26-12N1B diode array is also suitable for the design of high-speed DC/DC switching regulators and DC/DC converters.

The working principle of MDD26-12N1B diode array is simple and uses the properties of the materials inside the diode array to protect devices from unwanted power surges. It has two diodes connected in series, which are responsible for protecting the device from the reverse polarity input. The diodes are also responsible for maintaining the normal voltage flow through the device and providing an over-voltage protection.

The first diode in the circuit will sense the voltage reversal as it passes through and will block it, forcing it to travel in the opposite direction. This creates a reverse voltage path for the power, which allows only the desired amount of current to reach the device. The second diode in the array then serves to reduce the voltage spike and absorb any excess energy, preventing the device from being damaged.

The MDD26-12N1B diode array combines the efficiency and protection qualities of the two diodes in series to deliver superior performance and reliability. It also features a low leakage current and a high holding voltage of up to 12V, making it a great choice for protecting devices in a wide range of applications.
