The power electronics feeding AI data centers rarely make headlines, but they are quietly becoming a growth market — and Magnachip wants a bigger slice. On June 22, Magnachip Semiconductor Corporation (NYSE: MX) launched two new sixth-generation 600V Super Junction MOSFETs aimed at AI servers, EV charging systems and industrial power applications.
Magnachip designs and manufactures analog and mixed-signal power semiconductors, with operations centered in South Korea. The new devices carry low on-resistance ratings of 36 and 37 milliohms to cut conduction losses, integrate a Zener diode between the gate and source terminals for enhanced electrostatic discharge protection, and shrink chip size significantly versus the prior generation. The timing is the interesting part: research firm Omdia projects the discrete semiconductor market within computing and data storage will grow from approximately $3.7 billion in 2025 to approximately $5.9 billion by 2030, a compound annual growth rate of roughly 9 percent, as high-density, high-efficiency server power architectures proliferate alongside AI build-outs.
Magnachip competes against far larger power-semiconductor rivals, and a product launch does not guarantee design wins or meaningful revenue. This is market commentary, not investment advice — small-cap technology stocks are highly speculative and you can lose your entire investment.
