On November 28, 2025, Melexis, a globally renowned microelectronics engineering company, officially released the MLX91299, a new silicon-based RC snubber. Designed specifically for silicon carbide (SiC) power modules, this device brings significant breakthroughs to high-voltage power applications with its unique performance optimization, attracting widespread industry attention.
SiC devices have become a core choice in new energy vehicles and industrial applications due to their high-speed switching and high-voltage operation capabilities. However, issues such as high dV/dt and high-frequency oscillations limit their reliability. Leveraging its expertise in motor control and current sensing technology, Melexis developed the MLX91299, which innovatively integrates resistors and capacitors to efficiently suppress voltage spikes, eliminate oscillations, and reduce switching losses by up to 50%.
With a breakdown voltage of 1500V, this snubber is suitable for high-voltage scenarios like traction inverters and onboard chargers. Its compact design allows seamless integration inside power modules, compatible with sintering and welding processes, and maintains stable performance even at extreme junction temperatures of 200°C. It not only optimizes thermal management and power density but also simplifies assembly, reduces BOM costs, and significantly enhances system electromagnetic compatibility.
According to Ye Changsheng, Product Line Director at Melexis, "The MLX91299 is an ideal solution for protecting SiC modules, providing engineers with innovative flexibility." As the first member of Melexis's "protective devices" series, the product will continue to evolve alongside advancements in power module technology.
The launch of this new product will further promote the reliable application of SiC power modules in new energy vehicles and industrial control, injecting new momentum into industry development.Tags:#SiC#Semiconductor#Chinese chips
