Silicon carbide MOSFET SCT4026DTWHR

high-voltage resistancefor automotive applicationsSiC

Product overview
This device is a SiC MOSFET in a TSC3PAK package featuring a top-cooled structure. By locating the heat-dissipation surface on the package top, TSC3PAK achieves thermal performance comparable to conventional through-hole packages while remaining suitable for surface-mount assembly. A proprietary groove structure provides a creepage distance of 6.66 mm, supporting up to 1200 V AC peak in pollution degree 2 environments. Fourth-generation trench SiC technology delivers low on-resistance and fast switching for improved efficiency in power conversion circuits.

Key features

• AEC-Q101 qualified (Automotive grade)
• Large creepage distance: min. 6.66 mm
• Low drain-source on-state resistance (RDS(on), typ. 26 mΩ)
• Fast switching characteristics
• Fast reverse-recovery behavior
• Easy to parallelize
• Simple to drive
• Pb-free lead plating; RoHS compliant

Package / thermal / reliability
TSC3PAK package with a top-cooled design enables surface-mount assembly while delivering thermal dissipation comparable to traditional through-hole packages. The groove structure secures a 6.66 mm creepage distance and supports 1200 V AC peak under pollution degree 2, enabling safer insulation design and increased reliability for high-voltage applications.
