What is GaN?

Revolutionizing power engineering
 
Gallium Nitride, or GaN is revolutionizing the power engineering world by enabling high-speed, increased efficiency, and higher power density never before possible with Silicon MOSFETs.
 
GaN’s inherent lower gate and output capacitance enable MHz switching frequency operation while reducing gate and switching losses to increase efficiency. Unlike Silicon, GaN naturally lacks a body diode, which eliminated reverse recovery loss and further increases efficiency and reduces switch node ringing and EMI.
