With the continuous expansion of the new energy vehicle market, the performance requirements for electronic power devices are increasing day by day. Silicon carbide (SiC) MOSFETs, as representatives of the third-generation semiconductor materials, are gradually replacing traditional silicon-based devices and becoming core components in electric vehicle drive systems, on-board chargers, and DC converters, thanks to their outstanding properties such as high withstand voltage, low loss, and high thermal conductivity.
As a global leader in circuit protection and power control, Littelfuse's automotive-grade SiC MOSFET products strictly adhere to the AEC-Q101 certification standard, featuring high reliability, strong anti-interference ability, and a wide operating temperature range. They fully meet the strict requirements of modern automotive electronic systems.
Shenzhen Mingjiada Electronics Co., LTD., relying on over ten years of experience in electronic component distribution, has become an important supplier of Littelfuse automotive-grade SiC MOSFET products, providing comprehensive support from chip selection to technology implementation for automotive electronics manufacturing enterprises.
The technical advantages and value of SiC MOSFET
Silicon carbide materials have significant physical property advantages, which enable them to perform exceptionally well in high-temperature, high-frequency and high-power application scenarios. The critical breakdown field strength of SiC material is ten times that of silicon material. Its drift layer is thinner, the doping concentration is higher, and the on-resistance is lower.
The wide bandgap of 3.26eV enables silicon carbide devices to operate at junction temperatures up to 200°C or higher, significantly reducing leakage current and making them suitable for high-temperature environment applications. The thermal conductivity of SiC is three times that of silicon, which is conducive to the transfer of heat from the junction to the packaging shell, thereby enhancing power density and reliability.
Higher saturated electron drift velocities support ultra-high switching frequencies, significantly reducing the size and weight of passive components.
Compared with traditional silicon-based IGBTs, Littelfuse's SiC MOSFET modules can increase the inverter efficiency of electric vehicles by 3% to 5%, which means a longer driving range or a smaller battery size.
2. Product Features of Littelfuse Automotive SiC MOSFET
The Littelfuse automotive-grade SiC MOSFET product series features a variety of outstanding characteristics, meeting the demanding requirements of automotive electronic systems.
These products are designed with a wide temperature operating range (-55°C to +175°C), ensuring stable operation in extreme weather conditions and adapting to high-temperature environments such as engine compartments.
The high shock resistance design, through special packaging technology and internal structure design, has passed mechanical vibration and shock tests, meeting the vibration environment requirements during vehicle operation.
Low on-resistance is another major advantage. Advanced trench gate technology achieves milliohm on-resistance (RDS(on)), significantly reducing conduction losses.
The product also adopts thermally enhanced packaging, such as the 3x3mm flat lead package (WDFN) which features a wettable side wing design, saving space and improving thermal efficiency for compact automotive electronic modules.
