The 400CNQ045 array is a type of diode rectifier used in a variety of applications. It is comprised of four individual rectifiers connected in series which share a common anode lead. This type of configuration is used to provide an efficient, low voltage alternative to the commonly used MOSFET transistor arrays. It is well suited for the protection of equipment against electrical transients, and other surge conditions.

In various applications, the 400CNQ045 array functions as a bridge rectifier, providing full wave rectification for high frequency AC input signals. Using the phase controlled rectification method, the 400CNQ045 array can also be used for DC motor speed control, light dimming, and other power control systems. The rectifier is also commonly used in telecommunication systems and switching power supplies, due to its low voltage, low power consumption, and fast switching speed.

The 400CNQ045 array is composed of four individual rectifiers. Each individual rectifier is comprised of two separately activated temperatures-dependent silicon-controlled rectifiers (SCR). It is designed with a common anode that eliminates the need for two additional diodes and is designed to be used in bridge circuit applications. Each of the four SCRs is configured in an inverse parallel configuration, with the anode being connected to ground or its corresponding terminal point.

The 400CNQ045\'s working principle is based on the biased properties of SCRs. When the voltage across both SCRs with the same polarity exceeds their holding voltage, the current through both SCRs is constantly activated. This results in the 400CNQ045 array conducting current in both directions during phase controlled rectification. On the other hand, one of the SCRs experiences a negative potential of -0.4V, which is required for the 400CNQ045’s protection. This negative potential is mostly provided by a fast-reacting protection diode that switches off the protection in case of a very low holding voltage. This reduces the total power consumption without compromising the device’s efficiency.

In addition to its uses in rectification and power control, the 400CNQ045 array is also commonly used in high speed switching and noise and transient suppression applications. The 400CNQ045’s high speed makes it well suited to applications such as automotive, industrial and general purpose switching, where high speed response is essential. Its low-noise operation makes it ideal for use in noise suppression, where it can reduce unwanted noise and transients in sensitive circuits.

The 400CNQ045 array is an effective, low voltage alternative to MOSFET transistor arrays and is commonly used in a variety of applications, including high frequency AC input rectification, DC motor speed control, telecommunication systems, switching power supplies and noise suppression. Its combination of efficient protection and low voltage, low power consumption and fast switching speed has made it a popular choice for a variety of applications where a reliable, low-cost solution is required.
