750V, 45mΩ, 4-pin THD, Trench-structure, Silicon-carbide(SiC) power MOSFET

SCT4045DR is a SiC MOSFET that contributes to miniaturization and low power consumption of applications. This is a 4th generation product that achieves industry-leading low on-resistance without sacrificing short-circuit withstand time. This is a 4-pin package type with a driver source terminal that can maximize the high-speed switching performance that is a feature of SiC MOSFETs.

Advantages of ROHM's 4th Generation SiC MOSFET
This series has about 40% reduction in on-resistance and about 50% reduction in switching loss compared to conventional products. The 15V gate-source voltage makes application design easier.

  • User Guide
    • Application EVK - APEVK66001
    • Industrial 3.6kW Totem Pole PFC Application EVK
    • Various applications are equipped with AC/DC functions, and the Totem Pole PFC topology is the standard circuit.The TPPFCSIC-EVK-301 implements a single-phase AC/DC conversion stage in Totem Pole PFC topology. Key components are ROHM Gen.4 SiC MOSFETs (SCT4045DR) as the main high-frequency switching elements, as well as the BM61S41 single-channel isolated gate driver IC. In addition, SJ MOSFETs and auxiliary power supply, among other components from ROHM, were utilized to create a high-performance AC/DC circuit for single-phase operation.TPPFCSIC-EVK-301 reaches up to 98.5% efficiency at 230Vac.If this Totem Pole PFC reference design is coupled with a secondary stage of comparable efficiency, it becomes possible to achieve the 80+ Titanium target efficiency of power supply products. Moreover, this contributes to enhancing the Annual Performance Factor (APF) of air conditioners.

      This reference design consists of two boards. Each is shown below.
