Diodes - Rectifiers - Arrays (300CMQ040) consist of high voltage rectifiers capable of withstanding the high parasitic capacitance of large snubber capacitors and their components. This application field and working principle are crucial to consider when designing or building a system that will be driving a rectifier.

The 300CMQ040 application field and working principle is a highly dependable, fast and low-voltage switching rectifier. This unit features low on-state-resistance and low input capacitance, making it an ideal choice for applications where the fast switching typical of the device is required.

The device is designed for use in high voltage rectifiers for services including telecommunication, computer, and power distribution systems, as well as in power converters and DC-DC converters. It is constructed from two active high voltage rectifiers connected in parallel with a common anode and a common cathode. The maximum forward voltage of the device is rated at 25 volts, while the reverse voltage is 2 volts.

The device works in a very straightforward manner. When a positive voltage is applied to the anode side, the diode will draw current, and the current can be controlled by adjusting the voltage. The current will then be forced through a load, and the current will be regulated by the voltage applied on the cathode side. This is referred to as the forward bias.

The reverse bias of the device works in much the same manner, with the current being forced from ground through a load, but the current control is done by the voltage applied on the anode side. The high voltage rectifiers enable the design of systems with a high load-to-capacitor ratio, since it is capable of handling large currents sans the effect of parasitic capacitance. This ensures that the system will continue to run at a level of performance even when exposed to high voltage excursions.

The 300CMQ040 is rated for operation at temperatures ranging from -55°C to 125°C, and it has a maximum power dissipation of 2 W. It is conformal coated and rated for insulation to IP67 standard. The device is compliant with the RoHS standard.

When used in a high voltage rectifying system, the 300CMQ040 is highly reliable and will perform under a wide range of conditions. Its design enables it to handle the high parasitic capacitance of large snubber capacitors and their components. Additionally, it has low on-state resistances and low input capacitances, which make it a perfect choice for fast switching applications. It is rated for high voltages and temperatures, with a maximum power dissipation of 2 W. Finally, it is rated for IP67 for conformance to UL standard and RoHS compliant.
