Infineon Applied sciences AG unveils its first gallium nitride (GaN) transistor household certified to the Automotive Electronics Council (AEC) customary for automotive functions. The brand new CoolGaN automotive transistor 100-V G1 household, together with high-voltage (HV) CoolGaN automotive transistors and bidirectional switches, meet AEC-Q101.
This helps Infineon’s dedication to supply automotive options from low-voltage infotainment techniques addressed by the brand new 100-V GaN transistor to future HV product options in onboard chargers and traction inverters. “Our 100-V GaN auto transistor options and the upcoming portfolio extension into the high-voltage vary are an essential milestone within the growth of energy-efficient and dependable energy transistors for automotive functions,” stated Johannes Schoiswohl, Infineon’s head of the GaN enterprise line, in a press release.
The brand new units embody the IGC033S10S1Q CoolGaN automotive transistor 100 V G1 in a 3 × 5-mm PQFN package deal, and the IGB110S10S1Q CoolGaN transistor 100 V G1 in a 3 × 3-mm PQFN. The IGC033S10S1Q options an Rds(on) of three.3 mΩ and the IGB110S10S1Q has an Rds(on) of 11 mΩ. Different options embody dual-side cooling, no reverse restoration cost, and ultra-low figures of advantage.
These GaN e-mode energy transistors goal automotive functions reminiscent of superior driver help techniques and new local weather management and infotainment techniques that require larger energy and extra environment friendly energy conversion options. GaN energy units supply larger power effectivity in a smaller kind issue and decrease system value in comparison with silicon-based elements, Infineon stated.
The brand new household of 100-V CoolGaN transistors goal functions reminiscent of zone management and fundamental DC/DC converters, high-performance auxiliary techniques, and Class D Audio amplifiers. Samples of the pre-production automotive-qualified product vary at the moment are obtainable. Infineon will showcase its automotive GaN options on the OktoberTech Silicon Valley, October 16, 2025.
The put up 100-V GaN transistors meet automotive customary appeared first on EDN.
