Littelfuse introduces 1200V SiC MOSFETs with low on-resistance
At APEC 2018, San Antonio, Texas, USA, Littelfuse announces 1200V SiC MOSFETs that outperform silicon MOSFETs and IGBTs for fast switching in power conversion systems.
The two 1200V silicon carbide (SiC) n-channel, enhancement-mode MOSFETs are the latest products from a strategic partnership that Littelfuse formed with Monolith in 2015 to develop power semiconductors for industrial and automotive markets.
The LSIC1MO120E0120 and LSIC1MO120E0160 SiC MOSFETs offer low on-resistance (RDS(ON)) levels of 120 and 160-mOhms respectively. The SiC MOSFETs are designed for use as power semiconductor switches in a range of power conversion systems, outperforming silicon MOSFET counterparts substantially in terms of blocking voltage, specific-on resistance, and junction capacitances, says Littelfuse. They combine high operating voltages and fast switching that cannot be matched by traditional power transistors such as silicon IGBTs with similar current ratings and packages, continues Littelfuse.
The LSIC1MO120E0120 and LSIC1MO120E0160 SiC MOSFETs can be used in electric vehicles, industrial machinery, renewable energy products (e.g., solar inverters), medical equipment, switch-mode power supplies, uninterruptible power supplies (UPS), motor drives, high-voltage DC/DC converters and induction heating.
The 1200V SiC MOSFETs offer a reduction in passive filter components at the system level to support increased power density, for a design that’s optimised for use in high-frequency, high-efficiency applications. They also have low gate charge and output capacitance combined with low on-resistance which allows for
minimal power dissipation, higher efficiency and a reduction in the size and sophistication of the cooling techniques required, says Littelfuse.
The LSIC1MO120E0120 and LSIC1MO120E0160 SiC MOSFETs are available in TO-247-3L packages. Sample requests may be placed through authorised Littelfuse distributors worldwide.
