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.
## 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) with N-channel 100V, 300A silicon MOSFETs in TOLL packages for power management in EV batteries, charging systems, and power electronics.
**₹23,771 Crore Assam Facility**
The manufacturing will occur at Tata Electronics’ flagship facility in Jagiroad, Assam—a ₹23,771 crore ($3.2 billion) greenfield facility designed for high-volume semiconductor assembly and testing.
**Mass Production Timeline: Early 2026**
Target production commencement is early 2026, with the partnership formalized and facility ramping production capacity to support India’s EV component supply chain.
**300+ Skilled Jobs Creation**
The partnership is expected to create 300+ skilled positions in semiconductor assembly, testing, and quality assurance.
## Impact on Indian Industry
**EV Supply Chain Strengthening**
The partnership directly supports India’s EV sector by reducing import dependency for critical EV components and building domestic supply chain resilience.
**Technology Transfer & Capability Building**
ROHM’s involvement ensures technology transfer to Tata Electronics including advanced semiconductor assembly and testing techniques.
**Global Supply Chain Resilience**
Domestic production of automotive-grade power semiconductors contributes to global supply chain diversification away from concentrated sources.
