The first GaN-on-Si HEMT transistor from the world leader in power electronic components is today in mass production.

With the first applications in volume production, the GaN transistor market is becoming mature. Infineon, world leader in power electronics, has therefore stepped in. Infineon is a new entrant in the market for power GaN-on-Silicon transistors, with these components having been developed for industrial, telecom, datacenter switch-mode power supplies (SMPS). System Plus Consulting unveils this CoolGaN 600V technology from Infineon based on Panasonic’s patent. The latest device’s family is driving 600V and it is optimized for high frequency, high efficiency power conversion, which also reduces electromagnetic interference.

The IGOT60R070D1A from Infineon uses 600V GaN on Silicon E-mode High Electron Mobility Transistors (HEMTs) in a small outline (SO) package. The CoolGaN technology allows high switching frequency, which reduces energy loss. Moreover, the high frequency helps reduce the size and weight of the passive components.

CoolGaN technology allows the integration of an electrostatic discharge protection diode, produced using the same process as the HEMT transistor. The GaN and AlGaN layers are deposited by epitaxy on a silicon substrate. The enhancement-mode power GaN transistor has a p-HEMT structure. An ingenious field plate structure is processed in the metal layer.

This complete teardown analysis includes optical and SEM pictures of metal layers, delayering of the GaN, cross-section of the HEMT part and the diode part of the die. The report also provides an estimation of the production cost of the epitaxy, HEMT and the package.

Finally, the report compares the device with others CoolGaN family’s devices and  with 600V GaN on Si HEMTs from Panasonic.
