RUILIN SEMI Releases New 800V 1200A SiC Power Module with PHD Package for NEV & Energy Storage
Driven by the explosive growth of new energy vehicles, grid-scale energy storage and high-power industrial drive equipment, the power semiconductor industry is undergoing a massive shift from conventional silicon IGBTs to silicon carbide (SiC) solutions. Domestic semiconductor manufacturer RUILIN SEMI has officially rolled out its brand-new 800V 1200A SiC power module. This product adopts an advanced PHD packaging design and delivers an ultra-low 2mΩ on-resistance, showcasing outstanding performance in high power density scenarios. The module has completed full customer validation and entered mass production at a major tier-one equipment manufacturer.
Compared with traditional silicon power modules, SiC modules deliver obvious competitive edges in conversion efficiency, switching speed and system miniaturization. Global leading semiconductor suppliers including Infineon, ROHM, Wolfspeed and onsemi are also vigorously pushing the commercialization of SiC modules for high-voltage, high-current power conversion applications.
PHD Packaging: Optimized for Ultra-High Power Density
RUILIN SEMI’s new SiC power module leverages a dedicated PHD package structure, which is fully optimized for thermal dissipation and electrical dynamic performance.
Core advantages of the PHD package:
Minimized parasitic inductance inside the power loop
Enhanced continuous current carrying capability
Optimized layered heat conduction channel layout
Enables more compact overall system mechanical design
In high-power inverter equipment, packaging architecture directly determines long-term system efficiency and operational reliability. The PHD package shortens internal current paths and optimizes heat dissipation routing, allowing the SiC module to sustain stable, consistent operation under heavy continuous current loads.
2mΩ Ultra-Low On-Resistance Delivers Remarkable Efficiency Gains
Among all electrical parameters of SiC power modules, on-resistance (Rds(on)) is a core metric that directly dictates total system power loss.
RUILIN’s 800V 1200A SiC module achieves an ultra-low 2mΩ Rds(on) paired with automotive-qualified PHD packaging, drastically cutting conduction loss under high-current operating conditions.
This performance advantage creates tangible value for the following mainstream verticals:
Main traction inverters for new energy vehicles
Bidirectional power conversion systems (PCS) for energy storage stations
High-power industrial variable frequency drive systems
Grid-connected photovoltaic inverters
For all these devices, every reduction in power loss translates to higher overall energy efficiency and smaller, lighter cooling subsystems.

Perfect Match for NEV 800V High-Voltage Platforms & Energy Storage Systems
The 800V high-voltage architecture has become an irreversible mainstream trend for new energy passenger and commercial vehicles, driving rapid penetration of SiC power modules in vehicle main drive inverters.
High-current SiC modules bring three core upgrades to electric vehicle powertrains:
Higher inverter energy conversion efficiency
Reduced overall dimensions of power electronic assemblies
Lighter weight for the entire electric drive system
Meanwhile, energy storage power stations widely deploy high-capacity PCS converters, where SiC modules help boost system power density and round-trip energy efficiency.
RUILIN SEMI Continues Deep Investment in High-Power SiC Module Technology
As the domestic SiC industrial supply chain matures, high-current power modules have become an indispensable core building block for next-generation power electronic hardware. RUILIN SEMI will keep focusing R&D investment on high-power SiC die design, advanced packaging processes and high-efficiency power conversion system solutions.
The newly launched 800V 1200A SiC power module further enriches the company’s full SiC product portfolio, and provides a brand-new high-current power device option for OEMs developing new energy vehicles, grid energy storage and industrial power conversion equipment, while supporting customers to implement safer redundant hardware design schemes for end products.
