AlGaN/GaN HFET devices demonstrate remarkable performance. For commercial acceptance of this technology, long-term device stability must meet stringent industry standards. We review the current status of GaN reliability and contrast it with the requirement for commercial viability. Results analyzing degradation pertaining to buffer leakage and gate diode forward failure is presented
