The 444CMQ035 is a diode-rectifier array, which is an electronic component that contains multiple diodes and resistors stringed together in a circuit. It is well suited for current control, protection and rectification of power supplies and motor drives, as well as digital and analog systems.

This device is a single package with four independent diodes inside. Each diode has its own anode, cathode and an internal resistor connected in series to perform rectification. The anode and cathode terminals of the diode are connected in a common return line, so the internal resistor aids in voltage regulation for the diode.

The 444CMQ035 is designed to rectify AC signals up to 400 volts and guard against voltage transients within the range of 0.1 percent to 10 percent of full voltage. It is also designed to reduce harmonic distortion, especially in low frequency circuits, to preserve its many applications. This device is particularly well suited for operation in high frequency, radio frequency and power supply circuits.

The device is composed of four individual back to back diodes characterized by negative temperature coefficient. All four diodes have a built-in resistor that limits the current to 1.2A. The capacitance of this device is low at 3pF, making it a great choice for high frequency applications, as it can reduce any unwanted noise on the output voltage.

The 444CMQ035 has a relatively high current handling capacity up to 2A. Each diode is capable of handling up to 0.5A at 25˚C. With its relatively low voltage drop of 0.4V, it is also well suited for applications that require high efficiency power rectification and current control.

The device has a low forward voltage drop and reverse breakdown voltage of less than 4V. Its power dissipation rating is 4.5V with a temperature coefficient range of -0.115C/in2. It is relatively heat resistant and can endure operating temperatures of up to 150˚C. The 444CMQ035 comes in the industry standard TO-220 package and offers a wide range of mounting options, including through-hole and surface mount.

The working principle of the 444CMQ035 is simple but efficient. When an AC signal is applied to the device, the forward voltage of the diodes induces a corresponding current across it. This AC current is then converted to a rectified DC current due to the reverse biased nature of the diodes. The internal resistors aid in voltage regulation and reduce harmonic distortion. This device is thus highly suitable for rectification, voltage regulation and current control.

The 444CMQ035 is an innovative and highly integrated diode rectifier array that provides superior performance in applications requiring rectification and voltage regulation. With its low voltage drop and reverse breakdown voltage, the device is efficient while reducing harmonic distortion and providing high-efficiency power rectification. Its wide range of mounting options, heat resistance and simple but efficient working principle makes it a useful solution for many applications, from power supply to motor drives.
