­GaN switches typically have lower gate voltage ratings than silicon FETs. Most GaN manufacturers recommend a typical gate drive voltage of 5 V. Some have an absolute maximum rating of 6 V, which does not give much headroom between the recommended gate drive voltage and the critical threshold, above which would da
