Cyient Semiconductors has introduced a new GaN power IC family for the Indian market, developed using Navitas Semiconductor’s GaN technology. The initial lineup includes seven GaN power devices aimed at applications that include AI data center and telecommunications power systems, as well as e-mobility charging platforms.

The first-wave parts are described as 650 V-class devices, and Cyient lists the individual SKUs as 700 V GaN devices in DPAK packages with integrated drivers. The seven devices span on-resistance options from 120 mΩ to 330 mΩ, with variants called out for specific topologies including QR (quasi-resonant) and PFC/HS (power factor correction/high-side) use cases.

Cyient’s listed devices are:

• CYPG6148CQ: GaN 700 V, 120 mΩ, DPAK with driver (QR topologies)
• CYPG6148CP: GaN 700 V, 120 mΩ, DPAK with driver (PFC/HS topologies)
• CYPG6146CQ: GaN 700 V, 170 mΩ, DPAK with driver (QR topologies)
• CYPG6146CP: GaN 700 V, 170 mΩ, DPAK with driver (PFC/HS topologies)
• CYPG6145CQ: GaN 700 V, 210 mΩ, DPAK with driver (QR topologies)
• CYPG6144CQ: GaN 700 V, 260 mΩ, DPAK with driver (QR topologies)
• CYPG6143CQ: GaN 700 V, 330 mΩ, DPAK with driver (QR topologies)

For data center engineers, the immediate takeaway isn’t the brand-newness of GaN, it’s the packaging and integration level. Putting drive, control, and protection functions into a DPAK power device is a practical path to faster power-stage design cycles, especially in AC-DC front ends where layout, EMI behavior, and thermal paths can dominate iteration time.

The GaN ICs also include integrated EMI management and current sensing, and Cyient describes them as using industry-standard, high-thermal-performance packages. The target applications include consumer USB-PD chargers, laptop and mobile adapters, AC-DC power supplies, AI data center and telecommunications power systems, and e-mobility charging platforms.

Cyient and Navitas are working under a licensing arrangement in which Cyient will license Navitas’s GaN technology for use in India. Cyient will also act as a second source for select Navitas GaN devices already in mass production, positioning the relationship as a way to strengthen supply chain resilience and provide local support.

Suman Narayan, CEO of Cyient Semiconductors, said the launch “mark[s] our entry into high-performance power semiconductors with a strong roadmap for expansion,” adding that the devices are “designed to accelerate adoption and support next-generation power applications.”

Cyient expects to begin sampling the first set of GaN power products by June 2026.
