GaN's datasheets missing td(on)/td(off)/tr/tf
Free_WiFi:
I'm looking at this Gan Transistor from the official website of GaN Systems - GS-065-011-1-L
My trouble there's no specifications about these parameters :
td(on)/td(off)/tr/tf
In the meanwhile these parameters are present on the Infineon transistors like the : IGT60R190D1S
So what's the problem?
Why there's no specifications about td(on)/td(off)/tr/tf on every GaN transistors from the official datasheets?
T3sl4co1l:
They give Qg. What's it matter?

Marco:
The design note has tr/tf measurements ... 90/10 10/90 looks about 10 ns for 400V 8A, delay a bee's dick.
David Hess:
I agree with T3sl4co1l. The gate charge requirements matter more than the switching characteristics. Knowing the gate voltage waveform should be enough.

Then don't mess with GaN transistors. Seriously, don't. Use a SiC MOSFET if you want bleeding edge tech without so much blood.
