Why Leapers Semiconductor Selected the Melexis MLX91299 RC Snubber
Leapers Semiconductor develops advanced power modules designed for extreme operating conditions commonly found in electric mobility and charging infrastructure. These systems increasingly rely on silicon carbide power devices that operate at higher voltages and much faster switching speeds than traditional silicon.
The Melexis MLX91299 RC snubber directly supports these requirements by maintaining signal stability and reducing stress on sensitive SiC components, allowing power modules to operate safely at higher efficiency and switching frequencies.
Supporting Next-Generation SiC Power Architectures
As silicon carbide adoption expands across electric vehicles and charging equipment, the need for precise transient control becomes more important. High-speed switching, while improving efficiency, introduces strong voltage overshoot and electromagnetic interference.
