Magnachip Debuts 7th-Gen 24V MOSFET with 26% Smaller Chip for Foldables

MXMX

Magnachip has begun mass production of its 7th-generation 24V MXT LV MOSFET, reducing chip size by 26% and lowering Rds(on) by 31%, for battery protection in tri-fold smartphones supplied to a major global manufacturer. The Dual N-channel MOSFET cuts footprint by over 20% and integrates 2kV ESD protection.

1. Product Launch and Production Status

Magnachip has started mass production of its 7th-generation 24V MXT LV MOSFET (MDWC24D058ERH) designed for battery protection in tri-fold smartphones, with initial shipments to a major global smartphone manufacturer.

2. Technical Innovations and Benefits

The Dual N-channel MOSFET leverages Super-Short Channel FET technology to shrink chip size by roughly 26%, reduce Rds(on) by about 31%, and decrease PCM footprint over 20%, enabling slimmer device structures or larger batteries.

3. Applications and Customer Adoption

Beyond tri-fold smartphones, the device supports wearables and tablets, integrates over 2kV of ESD protection, boosts current density by 48%, and cuts heat generation through lower power loss.

4. Market Growth Forecast and Strategy

The sub-40V power MOSFET market is projected to expand from $4.2 billion in 2025 to $5.2 billion by 2029 at a 4.6% CAGR, with premium foldables driving demand; Magnachip plans to broaden its mobile power portfolio accordingly.
