Overview
Cyient Semiconductors has introduced India's first commercial gallium-nitride (GaN) power IC family, a set of seven monolithic devices rated at 650V. The chips integrate drive, control, protection, EMI management, and current sensing on a single die, using Navitas Semiconductor's AllGaN process under a licensing agreement announced in December 2025. The portfolio targets AC-DC conversion in AI data centers, telecommunications, consumer fast charging, industrial power systems, and e-mobility platforms.
What the chips do
The seven devices are built on Navitas's GaN technology and packaged in industry-standard DPAK packages. Compared to traditional silicon power MOSFETs, GaN enables higher switching speeds (up to 1 MHz without external drivers), lower conduction losses, and improved thermal efficiency. Cyient claims a 40% reduction in AC-DC conversion losses and power densities up to 100 W/in³ for edge-AI server applications. The integration eliminates the need for separate gate drivers, reducing component count and simplifying PCB layout.
The product lineup
Cyient has released seven specific part numbers, all 700V-rated (the family is marketed as 650V for application headroom):
- CYPG6148CQ – 120mΩ, DPAK, driver integrated, QR topologies
- CYPG6148CP – 120mΩ, DPAK, driver integrated, PFC/HS topologies
- CYPG6146CQ – 170mΩ, DPAK, driver integrated, QR topologies
- CYPG6146CP – 170mΩ, DPAK, driver integrated, PFC/HS topologies
- CYPG6145CQ – 210mΩ, DPAK, driver integrated, QR topologies
- CYPG6144CQ – 260mΩ, DPAK, driver integrated, QR topologies
- CYPG6143CQ – 330mΩ, DPAK, driver integrated, QR topologies
All devices integrate drive, control, and protection functions. The CP suffix variants are optimized for power-factor correction and high-side topologies; the CQ variants target quasi-resonant flyback designs common in USB-PD chargers and adapters.
Target applications
Cyient specifies four primary markets:
- Consumer fast charging: USB-PD chargers, laptop and mobile adapters
- AC-DC power supplies: Industrial and telecom power systems
- AI data center power: Edge-AI servers and rack-level power distribution
- E-mobility charging: 800V EV traction inverters and charging platforms
The 650V rating covers the majority of single-phase AC-DC applications. For 800V EV systems, the chips are used in auxiliary power stages or in multi-level topologies.
Supply chain and manufacturing
Under the licensing agreement, Cyient Semiconductors will serve as a second source for select Navitas GaN devices already in mass production, strengthening supply chain resilience for Indian customers. The company plans to expand its GaN portfolio through partnerships with local OSATs (outsourced semiconductor assembly and test providers). Over time, the licensing agreement is expected to enable domestic manufacturing of GaN power devices in India, though Cyient has not announced a timeline for fab-based production.
Sampling and availability
Cyient expects to begin sampling the first set of GaN power products by June 2026. Customers can request datasheets, samples, and technical support directly from Cyient Semiconductors. The company has published a product page at cyientsemi.com/power-products/gan-power.
Bottom line
Cyient's GaN family is a practical step for Indian power electronics designers who need high-efficiency, high-density AC-DC conversion without the complexity of discrete GaN FETs and external drivers. The licensing deal with Navitas gives Cyient access to proven, production-ready GaN technology, while the DPAK packaging and integrated driver simplify adoption. The real test will be pricing, availability, and whether the promised 40% loss reduction holds up in real-world designs. For now, it's the first domestic GaN IC option in India, and that alone makes it worth evaluating.
