There are only two main players in low–voltage GaN: EPC and GaN Systems, a fact mainly due to the complexity of using a standard package with low losses. GaN Systems wants to compete with EPC, the market leader, in the low-voltage HEMT market. System Plus Consulting unveils the GS61004B from GaN Systems, the latest device driving 100V and optimized for AC-DC converters and high-frequency, high-efficiency power conversion.
The GS61004B from GaN Systems is a GaN-on-silicon HEMT transistor packaged in the GaNpx embedded die package. This embedded die package is unique to the market in that it allows for high current capability. The GS61004B has a die size of around 4 mm2 and carries up to 45A, which means more than 10A/mm², almost 3x higher than the competition.
The GS61004B is packaged in an innovative embedded die package developed by AT&S (ECP® process). This package has no wire bonding, which reduces inductance, and its design increases heat management. The die’s new position in the package facilitates
enhanced thermal dissipation, and a simplification of the process reduces manufacturing time and cost.
Based on a complete teardown analysis, this report also provides an estimated production cost for the epitaxy and the package. Moreover, this report compares standard 100V Si MOSFETs and low-voltage GaN on Si HEMT.
