ROHM Semiconductor rolled out new N-channel power MOSFETs that are specifically designed for AI power supplies in data centers. The company said the lineup is all about cutting power losses by reducing the on-resistance (R DS(on)) of the FETs and increasing reliability by expanding their safe operating area (SOA). The R DS(on), the resistance between the drain and source terminals of the power FET, is one of the most important performance metrics for power devices.

High-performance AI chips are gulping down large amounts of power to handle training and inferencing. The Blackwell GPUs at the heart of NVIDIA's latest Al accelerators burn through as much as 1,200 W at peak loads. Such AI chips drive the power requirements in data centers to over 100 kW per rack, up from the current range of 15 to 30 kW.

What is the Double-Pulse Test? The double-pulse test (DPT) is the most widely adopted method for measuring the characteristics of these power semiconductors in hard-switching situations. It reveals valuable insights into the power device in dynamic conditions, giving engineers the ability to accurately gauge everything from energy losses during turn-on (Eon) and turn-off (Eoff) to current (di/dt) and voltage (dv/dt) slopes.

The environmental impact of an electronic device is closely tied to manufacturing all of its internal components, including chips. The carbon footprint of even a single chip extends throughout its entire lifecycle, starting with the extraction of raw materials and extending through the power-hungry manufacturing process. These steps contribute to carbon emissions-even before factoring in the electricity used by the final product over its operating life.

Silicon carbide (SiC) continues to carve out a place for itself in power electronics after decades of dominance by silicon. SiC-based power switches are becoming the gold standard in the three-phase EV traction inverters due to their ability to handle higher voltages with better thermal conductivity and faster switching speeds. Such features lead to better power efficiency and a reduction in system cooling requirements.
