Semiconductor Solutions for Servers

As environmental problems have become serious and efforts to conserve energy are commonly required in recent years, the amount of data handled has increased and the performance of equipment has improved. As a result,  power consumption of server (data center) is increasing and energy saving measures are required. The focus of these measures is the problem of heat generation. In addition to increasing the heat generated as a result of increased power consumption by servers and other equipment, it also consumes a lot of power to operate the air conditioning necessary to cool those equipment. Therefore, servers and other equipment must aim for efficient use of electricity and the accompanying reduction of heat generation. Toshiba's MOSFETs combine latest generation process with a high heat dissipation package, contributing to the realization of a highly efficient power supply even in high-load operation, and has a performance suitable for power supply circuits of equipment such as servers. In addition to the problem of heat generation, the challenges required of servers to maintain stable operation are becoming increasingly more and more. By using high-performance semiconductor products with various protective functions, such as Toshiba's photocouplers, eFuse ICs, and TVS diodes (ESD protection diodes), problems that affect stable operation can be solved.

• MOSFETs for power supply circuit enables high-efficiency operation by applying latest generation process
• High heat dissipation packages are used for MOSFETs to improve heat dissipation capability
• Optical coupling provides high isolation voltage and improves stability of signal line operation
• Compliance with New Safety Standards (IEC-62368-1 and others) (eFuse ICs, photocouplers)
• Useful application notes, reference designs, and other documents on the web save design cycle time
