Gejian Semi Products

Gejian Semi offers four main product categories: IGBTs (Insulated Gate Bipolar Transistors) for motor drives and power conversion applications, SiC MOSFETs (Silicon Carbide MOSFETs) for high-frequency and high-efficiency power applications, Power Modules including intelligent power modules with integrated drivers and protection, and Gate Drivers for IGBT and SiC MOSFET applications. Each category is designed to address specific power semiconductor needs across industrial, automotive, and renewable energy markets.

Review the product categories below to find the right Gejian Semi products for your application, or contact our FAE team for selection guidance.

Selecting the right Gejian Semi product requires understanding your application requirements: voltage rating (600V-1700V range available), current capacity based on load requirements, switching frequency (IGBTs for <50kHz, SiC MOSFETs for >100kHz), thermal constraints, and package type. For motor drives and industrial inverters, IGBTs offer excellent cost-performance. For high-efficiency applications like EV traction inverters, SiC MOSFETs provide superior performance. Power modules simplify design with integrated drivers. Our FAE team can provide detailed selection guidance based on your specific requirements.

Use our selection guides in each category or contact LiTong FAE team for personalized product recommendations.

Gejian IGBTs and SiC MOSFETs serve different application needs. IGBTs are bipolar devices combining MOSFET input characteristics with bipolar output characteristics, offering low conduction losses at high currents and excellent performance for motor drives and inverters operating below 50kHz. They are cost-effective for traditional power applications. SiC MOSFETs are unipolar devices using wide bandgap silicon carbide technology, enabling higher switching frequencies (100kHz+) with significantly lower switching losses. They are ideal for applications where efficiency, size, and weight are critical, such as EV traction inverters and solar inverters. SiC devices also offer better thermal performance and higher breakdown voltages.

Choose IGBTs for cost-sensitive applications below 50kHz. Choose SiC MOSFETs for high-frequency, high-efficiency applications. Contact our FAE team for detailed comparison.
