Industrial Automation MOSFET Lead Times Lengthen Amid Strong Demand and Foundry Constraints
Lead times for certain power MOSFETs crucial for industrial automation applications are extending. Strong Q2 demand and persistent foundry capacity constraints are impacting delivery schedules across several key suppliers.
Procurement teams in the industrial automation sector are reporting increased lead times for a range of power MOSFETs, particularly those targeting motor control, power conversion, and robotic applications. The extension, which began subtly in late Q1 2026, has become more pronounced in Q2, with some components now quoting 20-30 week lead times, up from a more typical 12-16 weeks. This trend is attributed to a confluence of robust demand from manufacturing modernization initiatives and enduring capacity limitations within the specialized foundry ecosystem for power semiconductors.
Key suppliers like Infineon Technologies, ON Semiconductor, and Nexperia are facing pressure as order backlogs grow. While these manufacturers have previously invested in expanding their internal and external foundry allocations, the incremental capacity brought online has been quickly absorbed by a resurgent industrial market. The complexity of manufacturing power MOSFETs, which often utilize mature process nodes but require specific fabrication steps and quality control, makes rapid scaling challenging without significant capital expenditure and time.
Several factors are contributing to the sustained demand. The global push towards Industry 4.0 and smart manufacturing continues to drive integration of advanced automation systems, each requiring a multitude of power management and switching components. Furthermore, the increasing adoption of robotics in various industrial settings, coupled with the electrification of industrial machinery, is intensifying the need for high-performance and reliable MOSFETs. This is layering demand on top of existing requirements from traditional industrial equipment.
Supply chain experts advise procurement professionals to re-evaluate their buffers and diversify their sourcing strategies. Engaging closely with distributors for visibility into allocation changes and exploring alternative component specifications or vendors capable of cross-referencing critical parts are becoming essential. Proactive order placement and long-term supply agreements are also being recommended to mitigate potential disruptions and secure continuity of supply for upcoming production cycles through late 2026 and into 2027.
