Made possible through Silicon Carbide (SiC) technology, power efficiency helps customers serve their users in a more sustainable way — including those in the data center industry. Choosing the right components, such as MOSFETs or Schottky diodes, can make measurable differences in server power supply efficiency and heat generation.

Sustainability and Energy Conservation

When a manufacturer calls a product sustainable, that refers to a specific design to minimize impact on the environment’s ability to sustain life. For electricity-powered products, the word “sustainable” most often signifies energy savings. However, when a product’s purpose is power delivery — such as powering critical data servers — it can be a challenge to energy conservation methods.

While data centers are key to many aspects of modern life, many do not realize their impact on power consumption: data centers consume 2% of all electrical energy in the U.S. Keeping those data servers functioning requires more than just delivering power to the servers, as up to 40% of data center energy consumption lies in cooling costs alone.

Silicon Carbide Power Devices are Powering the Way to Sustainability

Finding efficient power delivery methods positively impacts sustainability. In fact, every 0.1% efficiency improvement in data centers could power between 8,000 and 10,000 homes for one year. One way to effectively accomplish this task lies in Silicon Carbide power device usage. From 2010 to 2020, data center servers utilizing Silicon Carbide power devices will contribute 620 billion kWh in energy savings.

Wolfspeed’s 650 V SiC MOSFETs: Reliable, Efficient, Sustainable

Consider Wolfspeed’s 650 V SiC MOSFET family that enables customers to meet and exceed 80+ Titanium efficiency requirements for server power supplies by offering the lowest conduction and switching losses in the industry. Silicon Carbide MOSFET usage can result in fewer required components and lower Silicon Carbide component cooling requirements. When observing the scale of power components used in data centers, cooler-running components can significantly reduce cooling costs. SiC MOSFETs contribute to power component reliability — a vital feature for data server power supplies — and higher system-level efficiency, in part due to the low conduction losses supported by Silicon Carbide.

Wolfspeed Solutions for Sustainable Power

When coupled with Wolfspeed’s industry-leading 6th generation (C6D) Schottky diodes, the 650 V SiC MOSFET enables power supply designers to realize performance levels that meet or exceed the requirements of even the most demanding applications.
