GaN power ICs: Cyient launches seven 650V devices for AI data centers

Cyient Semiconductors has introduced a new GaN power IC family for the Indian market, built using Navitas Semiconductor’s GaN technology. The first wave includes seven devices aimed at power conversion use cases that show up in data center power shelves and telecom rectifiers, as well as fast chargers, industrial supplies, and e-mobility charging.

The parts are rated for power applications up to 650 V and come in DPAK packages. Cyient Semiconductors describes the devices as highly integrated GaN power ICs that combine drive, control, and protection functions, along with integrated EMI management and current sensing.

For data center engineers, the immediate relevance is less about the package style and more about supply chain and design reuse: a second-source path for GaN devices already in mass production can reduce risk for high-volume power designs, especially as operators push higher power density in rectifiers and front-end AC-DC stages. But “high efficiency” claims only matter once designers can validate switching behavior, EMI performance, and thermals in their own power stages and magnetics.

The GaN lineup includes CYPG6148CQ and CYPG6148CP (700 V, 120 mΩ, DPAK with driver), CYPG6146CQ and CYPG6146CP (700 V, 170 mΩ, DPAK with driver), plus CYPG6145CQ (700 V, 210 mΩ), CYPG6144CQ (700 V, 260 mΩ), and CYPG6143CQ (700 V, 330 mΩ). Cyient Semiconductors lists QR topologies for the CQ variants, and PFC/HS topologies for the CP variants.

Cyient Semiconductors said it will license Navitas’s GaN technology for use in India, and it will also act as a second source for select Navitas GaN devices already in mass production. The companies tied the work to a strategic collaboration they said was announced in December 2025.

Suman Narayan, CEO of Cyient Semiconductors, said, “Built on Navitas’ proven GaN platform, these highly integrated devices are designed to accelerate adoption and support next-generation power applications.” Chris Allexandre, President and CEO of Navitas Semiconductor, said the partnership “delivers a strong local support infrastructure for our customers.”

Cyient Semiconductors expects to begin sampling the first set of GaN power products by June 2026. More details are posted at cyientsemi.com/power-products/gan-power.
