Melexis drives efficiency in power electronics with a new product line, 'Protective Devices'

Tessenderlo-Ham, Belgium - March 05, 2026 - Melexis, a global microelectronics engineering company, announces an important expansion of its portfolio with the launch of a new product line: Protective Devices. This strategic move underscores the company's' commitment to driving innovation, safety, and extended battery autonomy in the rapidly evolving electric vehicle (EV) and energy management sector.

The new product line will be led by Billy Ye, Product Line Director for Protective Devices. He will focus on delivering highly reliable, specialized solutions that safeguard sensitive electronic components while maximizing the efficiency of high-voltage systems.

The first product launched in the new line is the MLX91299, a breakthrough solution designed as a game-changer for Silicon Carbide (SiC) power modules. These modules are fundamental to increasing the driving range and improving the efficiency of EVs. The MLX91299 is an integrated silicon-based RC snubber circuit that provides two critical benefits:

1. Protection: It mitigates high-frequency oscillations, voltage transients, and parasitic effects that occur during the fast switching of SiC devices, which are major sources of electrical stress and instability.
2. Power Saving & Range Extension: By effectively damping these high-speed effects, the snubber can reduce critical switching losses by up to 50% (according to initial measurements). This improved efficiency means less wasted energy as heat and more power delivered from the battery to the wheels, thereby helping to save power and directly extending the driving range of electric vehicles and many other industrial applications.

Marc Biron, CEO Melexis, commented: "The transition to e-mobility demands unprecedented levels of safety, efficiency, and robustness. Our Protective Devices product line is specifically engineered to meet these challenges. The MLX91299 is more than a protection device; it is a fundamental enabler of higher system efficiency, allowing designers to harness the full potential of SiC technology. This increased efficiency translates directly into better battery utilization and greater EV range for the end-user."

Looking ahead, Melexis also confirms further plans for future strategic growth in the key Asian market. In January 2026, the company already announced that Leapers, a global manufacturer of advanced power semiconductor modules, will incorporate the Melexis MLX91299 silicon-based RC snubber into its next-generation modules. This collaboration is expected to accelerate the development of specialized protective solutions for critical automotive and industrial systems and further strengthen Melexis' global position.
