Melexis Silicon-Based RC Snubber Adopted by Leapers, Jointly Advancing SiC Power Module Development

On January 13, 2026, Melexis announced that its integrated silicon-based RC snubber, the MLX91299, has been selected by power module manufacturer Leapers for use in a new generation of high-performance power modules. This collaboration aims to enhance the reliability and efficiency of silicon carbide (SiC) power semiconductors in automotive and industrial energy management systems.

Technical Solution: Integrated Snubber, Noise Suppression

As SiC devices see accelerated adoption in fields like electric vehicles and renewable energy, technical challenges such as voltage overshoot and electromagnetic interference under high-frequency, high-voltage operation have emerged. Melexis's MLX91299 effectively suppresses voltage spikes and oscillations by integrating resistance and capacitance into a single chip. It also features good thermal performance, helping to maintain a compact module structure and stable operation.

Collaboration Significance: Performance Enhancement and Promotion

Leapers stated that integrating this snubber helps fully realize the performance potential of SiC devices and addresses reliability issues in module applications. Melexis pointed out that the design is compatible with standard manufacturing processes, facilitating mass production adoption. Through this collaboration, both parties will provide more efficient and reliable power module solutions for demanding application scenarios.
