Executive Summary
GaN Systems is trying to compete with EPC, the market leader, on low voltages HEMT market. System Plus Consulting unveils GS61004Bfrom GaN Systems, the latest device driving 100V 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. It features a high-voltage breakdown voltage of 100V for a current of 45A (25°C), with lower switching losses.
The GS61004B is packaged is an innovative embedded die package developed by AT&S (ECP® process). This package has no wire bondingto reduce the inductance and a design to increase the heat management.
The new position of the die in the package allows to enhance the thermal dissipation and a simplification of the process reduces the timeand the cost of manufacturing.
Based on a complete teardown analysis, the report also provides an estimation of the production cost of the epitaxy and the package.
Finally, the report shows a comparison between the standard 100V Si MOSFETs and the low voltages GaN on Si HEMT.
