Cyient Enters Gallium Nitride Power Semiconductor Market

Gallium nitride power semiconductors are increasingly being adopted in high-efficiency power conversion systems where switching performance, thermal efficiency, and power density are critical design constraints. In this context, Cyient Semiconductors has launched its first range of gallium nitride power integrated circuits, introducing seven 650 V devices for the Indian market.

A licensed entry into India’s GaN power ecosystem
The launch marks Cyient Semiconductors’ entry into the power semiconductor segment through a strategic technology collaboration with Navitas Semiconductor announced in December 2025.

Under the agreement, Cyient Semiconductors will manufacture gallium nitride devices for the Indian market under licence from Navitas while also serving as a secondary production source for selected devices already in volume manufacturing. This model is intended to improve supply chain resilience while expanding domestic access to advanced power semiconductor technologies.

For India's semiconductor ecosystem, the move aligns with broader localisation efforts aimed at strengthening domestic electronics manufacturing and reducing supply chain dependence.

Why GaN matters in high-efficiency power conversion
Compared with conventional silicon-based power devices, gallium nitride supports higher switching frequencies, lower conduction losses, and improved thermal performance.

At the system level, these characteristics can enable smaller magnetics, reduced cooling requirements, lower energy loss, and more compact power electronics architectures. These advantages are particularly relevant in applications such as AI data centre power infrastructure, telecommunications power systems, fast charging platforms, and electric mobility systems where efficiency and thermal management directly affect operating cost and system design.

Seven integrated 650 V devices for multiple applications
The initial product family consists of seven integrated 650 V devices designed for a range of power electronics applications, including USB Power Delivery chargers, laptop and mobile adapters, AC/DC power supplies, data centre power systems, telecom infrastructure, and electric vehicle charging platforms.

The devices are packaged in DPAK form factors and integrate driver, control, protection, EMI management, and current sensing functions within a single package.

This integration reduces discrete component count and can shorten design cycles for OEMs seeking faster adoption of GaN-based power architectures.

Building a phased domestic semiconductor strategy
The initial launch relies on Navitas technology rather than an independently developed Cyient semiconductor platform, but the roadmap indicates a staged localisation strategy.

Cyient Semiconductors plans to expand the portfolio through partnerships with local outsourced semiconductor assembly and test (OSAT) providers, with longer-term plans to establish domestic manufacturing capability in India.

This phased approach reflects the practical constraints of semiconductor ecosystem development, where packaging, testing, qualification, and manufacturing capacity often scale incrementally rather than through immediate full-stack localisation.

Applications beyond consumer charging
While gallium nitride adoption initially gained traction in consumer fast-charging applications, the target application set here extends into industrial power electronics and digital infrastructure.

Edge AI systems, data centres, telecommunications networks, and e-mobility platforms increasingly require compact, thermally efficient power conversion hardware capable of handling higher performance densities.

By entering the GaN power IC segment through licensed production and local support infrastructure, Cyient Semiconductors is positioning itself within a part of the semiconductor market where demand is increasingly shaped by electrification and AI-driven power requirements.
