Transphorm introduces second 900 V GaN FET for three-phase applications

Transphorm, a provider of Gallium Nitride (GaN) semiconductors, has introduced its second 900 V Field-Effect Transistor (FET), the Gen III TP90H050WS. Transphorm’s devices now enable three-phase industrial systems and higher voltage automotive electronics to use GaN. The FET has a typical on-resistance of 50 mOhm with a 1000 V transient rating, offered in a standard… Read more »

SiC vs GaN semiconductors for EV power converters: Tech Opinion

Just as engineers are starting to get used to the advantages (and quirks) of silicon carbide (SiC ) devices, another semiconductor material joins the fray: gallium nitride, or GaN. Though there are some superficial similarities between these two materials, and even some overlap in their areas of best use, it is my opinion that only… Read more »
