SemiQ Previews Next-Generation 1700V SiC MOSFET Modules at Electronica 2026 - TimesTech

The 1700V class has been the most awkward gap in power semiconductors for five years—1200V is a bloodbath in EV traction, 3300V remains locked by Si IGBTs. SemiQ's module-level entry is a calculated bet: AI data centers and medium-voltage charging will elevate 1700V from transitional spec to dominant one. Technically, 1700V SiC MOSFETs demand substrate defect densities an order of magnitude tighter than 1200V parts. Six-inch wafer yield directly anchors the cost curve, and global substrate capacity remains heavily concentrated. Without a locked-in long-term supply deal, module gross margin compresses below 15%. On competition, Infineon's CoolSiC 1700V has been in volume production for three years; STMicroelectronics is advancing equivalent nodes. SemiQ's differentiation must come from module thermal architecture and system-level integration—chip parameters alone cannot dislodge incumbents' customer lock-in. Wolfspeed's financial distress opens a window, but it closes within 18 months. The real 24-month variable is 8-inch wafer mass production driving cost down, plus AI server power migrating to higher voltage rails. If 1700V modules hit 1.3x the system cost of Si IGBTs by 2027, industrial drive substitution becomes irreversible. This Electronica debut is less a product launch and more a signal to capital markets: we are still at the table.
