CVMOS200, CDMOS200, DMOS200, VMOS200 specifications

The Viking VMOS200, DMOS200, CDMOS200, and CVMOS200 are advanced products designed for telecommunications and power management applications. Each model showcases unique features and technologies that make them stand out in their respective fields.

The VMOS200 is built on the vertical MOSFET technology, allowing for optimized performance in high-power applications. This device excels in switching capabilities and minimizing conduction losses, leading to improved efficiency. The VMOS200 is ideal for use in power amplifiers and high-frequency applications, where reliable performance and thermal stability are crucial. Its rugged design ensures that it can withstand harsh environments, making it a preferred choice for industrial and aerospace applications.

Next, the DMOS200 employs a double-diffused MOSFET technology, which enhances its thermal performance and power handling capabilities. This model is particularly effective in low-voltage applications where efficiency is paramount. The DMOS200 features a low on-resistance characteristic, allowing for reduced energy loss during operation. Its fast switching speed enables high-frequency operation, making it suitable for RF amplifiers and motor drives.

The CDMOS200 introduces a charge-balanced design, optimizing the allocation of charge carriers within the device to minimize heat generation and improve efficiency. This model is tailored for demanding applications in communications where signal integrity and power efficiency are critical. With its high breakdown voltage and robust construction, the CDMOS200 can handle more demanding operational conditions, making it popular in cellular and satellite communication systems.

Lastly, the CVMOS200 combines the advantages of vertical and charge-balanced technologies, offering a versatile solution for a broad range of applications. This hybrid design provides high efficiency, exceptional reliability, and enhanced thermal management. The CVMOS200 is particularly well-suited for switching power supplies and audio amplification. Its compact footprint allows for integration into space-constrained designs while maintaining high performance.

In summary, the Viking series of devices—VMOS200, DMOS200, CDMOS200, and CVMOS200—offer a range of features, technologies, and characteristics tailored to meet the demands of modern power electronics and telecommunications. With their robust designs, high efficiency, and adaptability to various applications, these devices are integral components for engineers and designers looking to create cutting-edge technological solutions.
