onsemi Expands SiC Ingot Capacity in New York to Meet Surging EV Power Electronics Demand
onsemi has officially announced a significant expansion of its silicon carbide (SiC) ingot and substrate manufacturing facility in New York. This move is a strategic response to the rapidly escalating global demand for high-performance power modules in electric vehicles.
onsemi has initiated a substantial capacity expansion project at its silicon carbide (SiC) manufacturing site in New York, focusing on increasing the production of SiC ingots and substrates. This development is pivotal for the burgeoning electric vehicle (EV) market, which heavily relies on SiC technology for its power electronics due to its superior efficiency, thermal performance, and power density compared to traditional silicon-based components. The investment aims to alleviate future supply constraints for critical EV power modules.
The expansion targets a significant uplift in raw SiC material output, a foundational element for the company's vertically integrated SiC supply chain. By enhancing internal ingot production, onsemi aims to gain greater control over material quality and availability, thereby strengthening its position as a key supplier for automotive Tier 1s and OEMs. This strategic vertical integration is crucial for ensuring a stable and reliable supply of SiC power devices, which are integral to EV traction inverters, on-board chargers, and DC-DC converters.
Industry analysts indicate that the global demand for automotive-grade SiC power semiconductors is projected to grow aggressively over the next five years, driven primarily by the transition from internal combustion engine vehicles to EVs. onsemi's proactive capacity expansion is designed to capture a larger share of this growing market, positioning the company to capitalize on long-term EV production targets set by major automotive manufacturers worldwide. The increased output from the New York facility is expected to start contributing to the broader supply chain within the next 18-24 months.
Procurement engineers should monitor the ramp-up schedule of this facility closely. While immediate lead times for SiC components may not see a direct impact, the long-term implications for supply stability and potentially competitive pricing, as capacity outstrips demand, are significant. Diversification of SiC sourcing strategies remains paramount, but onsemi's enhanced capabilities offer a more robust supply avenue for critical power electronics.
