ROHM Launches AG16xFNxx Series MOSFETs for Automotive 48V Power Supply Systems

ROHM Advances 48V Automotive Power Architecture with Incremental MOSFET Rollout

By The Northwire Desk — AI Analysis Jun 17, 2026 · 16:00 6963 NaN
Executive Summary
  • ROHM Semiconductor has begun mass production of the AG16xFNxx Series, a new lineup of 80V power MOSFETs engineered specifically for 48V automotive power supply systems.
  • The devices utilize compact HPLF5060 and DFN3333 packages featuring Gull-Wing Leads and Wettable Flank Technology, alongside Copper Clip Junction Technology for improved thermal dissipation and high current handling.
  • Mass production commenced in April 2026, with online sales now available through ROHM and distributors DigiKey and Farnell.
  • The product line complies with automotive reliability standard AEC-Q101 and falls under ROHM's EcoMOS™ silicon power MOSFET brand.
  • Future roadmap includes package expansions, with TOLG (TO-Leaded with Gullwing) development already underway.
Material Impact
  • The release represents a standard product expansion within ROHM's established power semiconductor portfolio.
  • It targets the industry-wide transition from 12V to 48V automotive architectures, a trend projected for wider adoption around 2030.
  • No pricing, volume commitments, customer adoption metrics, or revenue impact are disclosed in the release.
  • The announcement aligns with a consistent historical pattern of incremental product updates rather than a strategic pivot or major contract win.
  • Given the lack of disclosed financial or operational scale, the immediate market impact is expected to be marginal.
