The aim of the collaboration is to combine Rohm's component development technology with TSMC's GaN-on-silicon process technology. This is intended to meet the growing demand for outstanding high-voltage and high-frequency characteristics for silicon-based power components.

Use in on-board chargers

Gallium nitride power components (GaN) are currently used in industrial applications such as power supplies and server power systems. TSMC supports GaN technology due to its potential environmental benefits in automotive applications such as on-board chargers and inverters for electric vehicles.

Deepen partnership

The partnership builds on the collaboration between Rohm and TSMC in GaN power devices. In 2023, the Japanese semiconductor manufacturer introduced TSMC's 650-V GaN HEMT technology. This is increasingly used in devices for consumer and industrial applications as part of Rohm's EcoGaN series. This includes the 45-W AC adapter "C4 Duo" by Innergie, a brand of Delta Electronics, Inc. (se)
