ROHM has commenced mass production of its SCT40xxDLL series silicon carbide (SiC) MOSFETs in TO-Leadless (TOLL) packages, offering a significant 39% improvement in thermal performance compared to conventional TO-263-7L packages with equivalent voltage ratings and on-resistance. The new series is designed to meet the growing demand for compact, high-power components in applications such as AI server power supplies and energy storage systems (ESS), where power density and miniaturization are increasingly critical.
As modern industrial and consumer equipment evolves, applications such as compact photovoltaic (PV) inverters and high-efficiency server systems face dual requirements: increasing power capability and reduced system size. This is especially true for power factor correction (PFC) circuits in slim-profile “pizza box” server power supplies, where discrete semiconductors must conform to strict thickness constraints of 4 mm or less.
ROHM’s SCT40xxDLL series responds to these requirements with a compact 2.3 mm low-profile form factor—approximately 50% thinner than traditional equivalents—and a reduced component footprint by about 26%. The series also distinguishes itself with a rated drain-source voltage of up to 750 V, surpassing the standard 650 V found in many TOLL package MOSFETs. This higher voltage rating contributes to increased surge voltage tolerance, lower gate resistance requirements, and reduced switching losses.
The SCT40xxDLL lineup includes six models with typical on-resistance values ranging from 13 mΩ to 65 mΩ. Maximum current ratings span up to 120 A, depending on the device, making them suitable for a wide range of high-performance power conversion systems. Mass production began in September 2025.
