Do GaN FETs have internal diodes?
Gallium Nitride (GaN) power FETs have been in production for over 10 years by many manufacturers. Sometimes the schematic symbol for GaN FETs includes a diode, and sometimes not. This talk explores the structure of GaN FETs, and whether or not they have an internal diode. What is the reverse conduction performance, and how can engineers take advantage of the reverse conduction characteristics in power designs. Also covered in this talk is a review of recent advances in GaN FETs and GaN ICs, reliability study advances, and also controllers and gate drivers. The lecture concludes with a look at the near future of GaN devices.

Biography:
Brian Miller joined EPC in 2016, where he is the senior field applications engineer for eastern North America. He has over 30 years of experience in power electronics, as a design engineer and as a field application engineer. At IBM and Sony Ericsson he designed small, efficient power supplies and battery chargers, and designed a custom analog controller IC for notebook PC DC/DC and battery charging. Previous to EPC, Brian was a field application engineer for Semtech, where he was involved in designs for DC/DC, AC/DC, LED lighting, TVS, and other areas. He has authored patents, articles, and talks. Brian received his MSE and BS degrees from Duke University in Durham, North Carolina.
