Wolfspeed & Rohm Reduce Mid-range SiC Chip Wafer Allocation, Global Automotive SiC MOSFET Lead Time Extended to 36–52 Weeks Accompanied by Price Increase of 12%~24%

Wolfspeed and Rohm, two leading global SiC chip manufacturers, adjusted internal wafer allocation plans in the third quarter of 2026. The majority of 6-inch and 8-inch SiC substrate production capacity is assigned to high-voltage premium automotive SiC chips, while the monthly output quota of mainstream mid-range SiC MOSFET and SiC diodes is drastically cut down.
Alongside capacity compression, both brands carried out the second round of price hikes within half a year. The quotation of all automotive-grade discrete SiC chips and power modules rose by 12% to 24%. Authorized distributors can only obtain limited fixed monthly allocations, and the delivery cycle of newly placed orders for conventional automotive SiC chips has been prolonged to 36–52 weeks.
The scattered spot goods circulating on the market are mixed with refurbished dismantled chips and recoded counterfeit products, which cannot meet AEC-Q100 vehicle-grade reliability standards.

LXBCHIP has stocked a large number of genuine original sealed SiC chips from Infineon, Wolfspeed, Rohm and ON Semiconductor in advance. All chips have traceable batch codes and complete official certification. We provide sample urgent delivery, batch split shipment and full BOM matching services for power semiconductors, helping customers avoid long factory waiting periods and continuous price increases.

Conclusion

The shortage of automotive SiC chips will last until the first half of 2027. Procurement personnel need to lock spot inventory in advance to guarantee stable material supply. Please contact our sales team to check real-time stock and apply for bulk preferential prices.

Wolfspeed & Rohm Cut SiC Wafer Allocation For Mid-range Automotive Chips, Global Vehicle-grade SiC MOSFET Lead Time Extended to 36–52 Weeks Along With New Round Price Increase

Wolfspeed and Rohm, two leading global SiC chip manufacturers, have adjusted internal wafer allocation schemes in Q3 2026. They concentrate most 6-inch and 8-inch SiC substrate production capacity on high-voltage premium automotive SiC chips, drastically reducing the monthly output quota of mainstream mid-range SiC MOSFET and SiC diode chips used for on-board power conversion.
Accompanied by capacity compression, both manufacturers launched the second price increase within half a year, with quotation rising 12%~24% for all automotive SiC discrete chips and power modules. Authorized global distributors can only receive limited fixed monthly allocations, and new order lead times for conventional automotive SiC chips have been prolonged to 36–52 weeks.
Circulating spot stocks in the market are mixed with refurbished disassembled chips and recoded counterfeit devices, which cannot meet AEC-Q100 vehicle-grade reliability standards.

LXBCHIP pre-stocked large quantities of genuine original sealed SiC chips from Infineon, Wolfspeed, Rohm and onsemi. All chips have traceable batch codes and complete official certification. We support sample urgent delivery, batch separate shipment and full BOM matching service for power semiconductors, helping customers evade long factory waiting cycles and successive price hikes.

Conclusion

Shortage of automotive SiC chips will persist until the first half of 2027. Purchasers should lock spot inventory in advance to ensure continuous material supply. Contact our sales team to check real-time stock and apply for bulk preferential prices.
