With the rapid development of new energy vehicles, grid-scale energy storage systems, and high-power industrial drives, power semiconductor devices are gradually transitioning from traditional IGBTs to SiC technology. Recently, domestic manufacturer RUI LIN Semiconductor (RUILIN SEMI) launched a new 800V 1200A SiC power module. This product adopts an advanced PHD package structure and achieves an ultra-low on-resistance of 2mΩ, demonstrating significant advantages in high-power density applications. It has successfully passed verification and entered mass production at a major industry player.
Compared to traditional silicon-based power modules, SiC modules offer clear benefits in efficiency, switching speed, and system size. Currently, manufacturers including Infineon Technologies, ROHM Semiconductor, and Wolfspeed are also continuously promoting the adoption of SiC modules in high-voltage, high-current applications.
PHD Package: Designed for High Power Density ApplicationsThe SiC module recently launched by RUILIN SEMI adopts the PHD package structure, a design optimized for both thermal management and electrical performance.
The main advantages of the PHD package include:
· Lower parasitic inductance
· Higher current-carrying capacity
· Optimized heat dissipation path design
· More compact system structure
In high-power inverter applications, the package design directly impacts system efficiency and reliability. The PHD package enables stable operation even under high current conditions by optimizing current paths and heat dissipation structures.
Efficiency Improvement Brought by 2mΩ On-Resistance
Among the critical parameters of SiC modules, on-resistance (Rds(on)) is a key indicator affecting system efficiency.
The on-resistance of this RUILIN 800V 1200A SiC module is as low as 2mΩ (PHD automotive-grade standard package), significantly reducing conduction losses under high-current operating conditions.
This advantage is particularly evident in the following application scenarios:
· New Energy Vehicle Main Drive Inverters
· Energy Storage PCS Bidirectional Converters
· High-Power Industrial Drive Systems
· Photovoltaic Inverters
In these systems, every reduction in power loss translates to higher system efficiency and lower cooling requirements.

Targeting New Energy Vehicles and Energy Storage Systems
As the 800V high-voltage platform increasingly becomes a trend in new energy vehicle development, the application of SiC modules in main drive inverters is rapidly increasing.
High-current SiC modules help vehicle systems achieve:
· Higher inverter efficiency
· Smaller power module size
· More lightweight electric drive systems
Simultaneously, in energy storage systems, high-power PCS equipment is increasingly adopting SiC modules to enhance system power density and overall efficiency.
RUILIN Continues to Advance SiC Power Module Technology
As the SiC industry chain matures, high-current power modules are becoming a crucial component of future power electronic systems. RUILIN will continue its technological investment in high-power SiC modules, advanced packaging technologies, and high-efficiency power conversion solutions.
The release of this 800V 1200A SiC module not only further expands the company's SiC product line but also provides a new high-current solution for new energy vehicles, energy storage systems, and industrial power electronics applications, ensuring safer redundant design for customer products.
