650V Enhancement Mode GaN Transistor

The GS66502B is an enhancement mode GaN-on-silicon power transistor. The properties of GaN allow for high current, high voltage breakdown and high switching frequency. GaN Systems innovates with industry leading advancements such as patented Island Technology® and GaNPX® packaging. Island Technology® cell layout realizes high-current die and high yield. GaNPX® packaging enables low inductance & low thermal resistance in a small package. The GS66502B is a bottom-side cooled transistor that offers very low junction-to-case thermal resistance for demanding high power applications. These features combine to provide very high efficiency power switching.
