Gallium Nitride (GaN)
CoolGaN™ 400V and 600V e-mode GaN HEMTs
With CoolGaN™ 400V and 600V e-mode GaN HEMTs Infineon brings GaN technology to the next level.
Gallium Nitride (GaN) offers fundamental advantages over Silicon. In particular the higher critical electrical field makes it very attractive for power semiconductor devices with outstanding specific on resistance and smaller capacitances compared to Silicon switches, which makes GaN HEMTs great for high speed switching.
Infineon CoolGaN™ technology is built to fully exploit the benefits of GaN. Our 400V and 600V CoolGaN™ e-mode HEMTs are offerd for consumer and industrial applications such as server, telecom, wireless charging, adapter and charger, and are qualified well beyond the standards. Infineon's enhancement mode GaN HEMTs are based on the most robust and performing concept on the market. Our 400V and 600V CoolGaN™ HEMTs focus on high performance and robustness and will add significant value to a broad variety of systems across many applications.
How does a GaN transistor work?
Using a p-GaN gate structure, Infineon CoolGaN™ works similar to conventional silicon MOSFETs with enhancement mode gate drive bias. When a positive gate voltage is applied, electrons are accumulated and form a low resistance channel in a lateral twodimensional electron gas (2DEG) layer between drain and source.
Unlike silicon MOSFETs with PN junction body diodes, GaN devices conduct reverse current as one of the switching states, eliminating reverse recovery charge which is a major source of switching noise.
CoolGaN™ transistors are the power devices with the best performance available on the market. They are built with the most reliable GaN technology, tailormade for the highest efficiency and power density in switch mode power supplies.
Infineon's 400V and 600V CoolGaN™ e-mode HEMTs enable 98%+ system efficiency and help customers to make their end products smaller and lighter. The impressive Figure or Merits (FOMs) of 600V CoolGaN™ transistors translate into valuable application benefits.
Infineon GaN quality
The qualification of GaN switches requires a dedicated approach, well beyond existing silicon standards: Infineon holistically aproaches the quality of GaN devices and qualifies GaN devices well beyond the standards without any compromise on long term quality and reliability.
Thourogh understanding of mission profiles and verified failure models, based on accelerated test conditions are integral part of our qualification approach and ensure that lifetime and quality are fully met in the target applications.
