VS-20CTQ040PBF

VS-20CTQ040PBF is part of a new generation of high-efficiency IGBT arrays specifically designed for industrial applications, such as home appliances, motor control and automotive. This device, along with its predecessor VS-20CTQ020PBF, is the industry\'s most efficient IGBT array with on-state resistance of only 2 mΩ/500 A in an ultra-small package. This innovative device is equipped with a powerful triple-diffused planar IGBT chip, providing increased voltage and current capability and excellent thermal characteristics.

A VS-20CTQ040PBF array is typically used for rectifying high-voltage AC power or for controlling AC power. It contains four series-connected high-voltage hYBL36P bipolar transistors (BJTs) with enhanced VCE ripple capabilities, connected in parallel without base resistors. This creates an efficient, yet highly controllable, rectifier array with a total VCE-value of 4 x 50 V. The hYBL36P devices possess better temperature dependencies than the corresponding standard models hVBL36P (when driving ± 20 V V DD@ 1 A each), enabling improved efficiency along with optimized switching times.

In terms of performance and efficiency, the VS-20CTQ040PBF array has many advantages compared to other arrays. It provides superior thermal performance with up to 97% power conversion efficiency, as well as short delay and recovery times. Furthermore, the device exhibits low EMI noise and can exceed the requirements for industrial and automotive application. The device also enables lower thermal stress and current stress to the switching elements, delivering improved reliability and extended lifetime for all stages of power conversion and motor control.

In terms of application fields, the VS-20CTQ040PBF array is mainly used in power factor correction (PFC) applications, as well as battery chargers, DC-DC converters, AC-DC converters, motor drives and inductive power applications. Its characteristics enable superior thermal performance, improved efficiency and fast switching times. The device is also suitable for high-frequency, hard-switched DC/DC converters, since its low switching losses and superior thermal characteristics help reduce temperature peaks and improve overall efficiency.

As far as the working principle of the VS-20CTQ040PBF array is concerned, the device uses four series-connected IGBTs to rectify high-voltage AC power. This power rectification process is achieved through the manipulation of electron flow during the on/off state of the device. When a signal is induced on the IGBT, it attracts electrons from one side and collecting them on the other, thereby creating an imbalance in the number of electrons. This electron imbalance creates a voltage difference, which in turn allows for the flow of electric energy. By controlling the on/off switching of the IGBT, the power rectification process is achieved. Furthermore, the device is equipped with an internal Schottky diode, which provides it with over-voltage protection from AC power surges. This helps ensure that the device is not damaged by transient over-voltages.

The VS-20CTQ040PBF array is a powerful and highly efficient device that is suitable for a wide range of industrial and automotive applications. Its enhanced thermal characteristics, low EMI noise, high-power efficiency and low switching losses make it a perfect choice for power factor correction, battery charging, DC/DC converters and motor drives. Furthermore, its robust and reliable design allow it to withstand the rigors of industrial and automotive applications, ensuring superior performance and longevity. The device\'s efficient rectifying capability and over-voltage protection also help to maximize its use in various industrial and automotive applications.
