The MBRT40040RL, a rectifier diode array made by ON Semiconductor, is a surface mount power diode device with four diodes in a common−cathode configuration. It has a low forward voltage drop of 0.45 V and a peak reverse voltage of 400V. It offers low reverse leakage current and excellent forward current handling capabilities for improved power efficiency. The MBRT40040RL is suitable for various power supply, rectification and motor control applications.

An array of diodes has a common cathode, meaning there is one cathode shared by all the diodes in the array. In the case of the MBRT40040RL, each diode has a peak reversed voltage of 400V. This means the total peak voltage that can be reversed across the entire array is 400V, with each of the four diodes in the array being able to handle up to 400V of reversed voltage. As a result, the MBRT40040RL is suitable for circuits that require high reversed voltages. In addition, it has a low forward voltage drop of 0.45V, making it suitable for power supply and rectification applications that demand a low forward voltage drop.

The MBRT40040RL is also designed with a built-in protection feature that prevents it from being damaged by over-voltage conditions. The protection feature allows the MBRT40040RL to handle up to a peak reverse voltage of 400V without being damaged. This feature makes it suitable for use in circuits that may be subjected to over-voltages due to noise, transients, and other sources.

The MBRT40040RL also has excellent forward current handling capabilities for improved power efficiency. The four diodes in the array can handle up to 9A of forward current. This means that the total forward current rating for the entire array is up to 36A. This makes it suitable for applications that require higher power efficiencies.

As a motor control device, the MBRT40040RL can be used to enable or disable the motor. With four diodes in series, it can be used to control the current flowing through the motors in order to maintain a constant voltage or current level. This feature makes the device suitable for motor control applications such as variable speed drives, brushless DC motors, and servo systems.

In summary, the MBRT40040RL is an ideal power diode array for applications that require higher voltages, lower forward voltage drops, and better power efficiency. Its four diodes in a common−cathode configuration together with its built-in protection feature makes it suitable for a variety of power supply, rectification and motor control applications.
