Tata Electronics has entered a strategic partnership with Japan’s ROHM Co., one of the world’s leading semiconductor manufacturers, to assemble and test automotive-grade power semiconductors in India. Mass production is targeted for early 2026 at Tata Electronics’ ₹23,771 crore ($3.2 billion) facility in Jagiroad, Assam. This partnership marks a significant step in building India’s domestic automotive semiconductor supply chain and reducing import dependency.
The Tata Electronics-ROHM partnership represents a critical milestone in India’s quest to build indigenous semiconductor manufacturing capabilities, particularly in the automotive sector. As electric vehicles accelerate globally and India targets aggressive EV adoption, the availability of reliable, domestically manufactured power semiconductors becomes strategically essential.
Key Developments
Strategic Partnership Agreement Signed
Tata Electronics and ROHM have entered into a formal partnership to jointly manufacture automotive-grade power semiconductors in India. ROHM brings advanced semiconductor design expertise and global quality standards, while Tata Electronics provides manufacturing infrastructure and India-based production capability.
Automotive-Grade Power Semiconductors Focus
The partnership specifically targets automotive-grade power MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistors):
– Product focus: N-channel 100V, 300A silicon MOSFETs in TOLL packages
– Application: Power management in EV batteries, charging systems, and power electronics
– Quality standard: Automotive-grade certification meeting global OEM requirements
₹23,771 Crore Assam Facility
The manufacturing will occur at Tata Electronics’ flagship facility in Jagiroad, Assam with investment of ₹23,771 crore ($3.2 billion) in a greenfield facility designed for high-volume semiconductor assembly and testing with advanced assembly, testing, and packaging capabilities.
Mass Production Timeline: Early 2026
Target production commencement is early 2026 with the partnership currently formalized and the facility ramping production capacity. Output will ramp to support India’s EV component supply chain serving both Indian and international markets.
