Innovative Design of SiC MOSFETs
ROHM Semiconductor has embarked on an exciting new chapter by launching a series of silicon carbide (SiC) MOSFETs designed specifically for high-power applications, all presented in a compact TOLL (TO-Leadless) package. This innovative design not only enhances thermal performance—achieving an impressive 39% improvement compared to conventional TO-263-7L packages—but also meets the increasing demands for miniaturization in the industry. The result is a product line that caters perfectly to the needs of modern industrial equipment, notably server power supplies and energy storage systems (ESS) where power density is becoming a critical factor.
Meeting the Demand for Miniaturization
In recent years, there has been a significant shift towards higher power ratings across various applications, particularly within AI servers and compact photovoltaic (PV) inverters. Concurrently, this shift has prompted a strong demand for miniaturization, creating a unique challenge for power MOSFETs as they need to maintain high power density. ROHM’s latest MOSFETs effectively address this by delivering a reduced component footprint—approximately 26% smaller than previous models—and an astonishing low profile thickness of 2.3mm. This is particularly beneficial for slim power supplies, commonly referred to as 'pizza box' types, which require discrete semiconductors to be 4mm or less in thickness.
Enhanced Product Features
These SiC MOSFETs are distinguished not only by their form factor but also by their operational capabilities. While many standard TOLL package products are restricted to a maximum drain-source voltage rating of 650V, ROHM’s cutting-edge products can operate at voltages up to 750V. This elevated voltage rating translates into lower gate resistance and a substantial safety margin against voltage surges, ultimately helping to minimize switching losses. The product lineup features six models with varying on-resistance values ranging from 13m? to 65m?, with mass production of these devices having commenced recently.
Versatile Applications
The versatility of ROHM's new SiC MOSFETs cannot be overstated. These components are well-suited for a range of applications, from industrial power supplies for data centers to consumer electronic devices. High-density power supplies for AI servers, PV inverters, and energy storage systems stand to benefit immensely from the enhanced performance and efficiency offered by these new devices.
Commitment to Quality and Innovation
A key part of ROHM's strategy is an unwavering commitment to quality and innovation. Their EcoSiC™ brand specifically focuses on silicon carbide technology, known for outperforming traditional silicon-based devices. Development efforts encompass everything from wafer fabrication to quality control processes, allowing ROHM to solidify its status as a leading supplier in the SiC marketplace. With an integrated production system in place, they ensure that each component meets rigorous standards, thus reinforcing their reputation for reliability.
