Infineon launches CoolGaN Transistors 650V G5 product family
Infineon Technologies AG of Munich, Germany has strengthened its gallium nitride (GaN) portfolio by launching a new family of high-voltage discretes, the CoolGaN Transistors 650V G5. Target applications range from consumer and industrial switched-mode power supplies (SMPS) such as USB-C adapters and chargers, lighting, TV, data-center and telecom rectifiers to renewable energy and motor drives in home appliances.
The latest CoolGaN generation is designed as a drop-in replacement for CoolGaN Transistors 600V G1, enabling rapid redesign of existing platforms. The new devices provide improved figures of merit to ensure competitive switching performance in focus applications. Compared with key competitors and previous product families from Infineon, the CoolGaN Transistors 650V G5 offer up to 50% lower energy stored in the output capacitance (Eoss), up to 60% improved drain–source charge (Qoss) and up to 60% lower gate charge (Qg), it is reckoned. Combined, these features result in what are claimed to be excellent efficiencies in both hard- and soft-switching applications. This leads to a significant reduction in power loss compared with traditional silicon technology, ranging from 20–60% depending on the specific use case.
These benefits allow the devices to operate at high frequencies with minimal power loss, resulting in superior power density, the firm says. The CoolGaN Transistors 650V G5 enable SMPS applications to be smaller and lighter or to increase the output power range in a given form factor.

The new high-voltage transistor product family offers a wide range of RDS(on) package combinations. Ten RDS(on) classes are available in various SMD packages, such as ThinPAK 5x6, DFN 8x8 , TOLL and TOLT. All products are manufactured on high-performance 8-inch production lines in Villach (Austria) and Kulim (Malaysia). In the future, CoolGaN will transition to 12-inch production. This will enable Infineon to further expand its CoolGaN capacity and ensure a robust supply chain in the GaN power market, which is expected to reach $2bn by 2029, according to Yole Group’s ‘Power GaN 2024’ report.
A demo featuring the CoolGaN Transistors 650V G5 is being showcased in booth 502 (hall C3) at electronica 2024 in Munich (12–15 November).
The CoolGaN Transistor 650V G5 product family can be ordered from Infineon now, and from e-commerce distributors in the coming weeks.
