Magnachip Semiconductor Corporation announced the launch of its 24‑volt MXT LV MOSFET, model MDWC24D058ERH, a 7th‑generation battery‑protection device engineered for next‑generation tri‑fold smartphones, wearable devices, and tablets.
The new MOSFET incorporates Magnachip’s proprietary Super‑Short Channel FET technology, shrinking chip size by 26% and lowering on‑resistance by 31% compared with earlier models. It also delivers a 20% reduction in the footprint of the battery‑protection circuit module board, a 48% improvement in current density per unit area, and electrostatic‑discharge protection exceeding 2 kV.
The silicon power MOSFET market below 40 V is projected to grow from roughly $4.2 billion in 2025 to $5.2 billion in 2029, a compound annual growth rate of about 4.6%. Magnachip’s launch positions it to capture a share of this expanding segment, reinforcing its strategy to lead in high‑performance power devices for advanced mobile platforms.
The device is already in mass production and has been supplied to a major global smartphone manufacturer, demonstrating early commercial adoption and validating the product’s performance in real‑world applications.
This 7th‑generation release builds on the company’s earlier 8th‑generation launch in 2024, further solidifying Magnachip’s leadership in power MOSFETs for high‑density, high‑efficiency mobile and wearable markets.
