I want to spark another discussion to try and get people's experiences and impressions on GAN's right now. My understanding of the market is this:
Transphorm
GAN Systems
EPC
TI
On Semi
Infineon
Any other comments thoughts or impressions?
Anyone using these or know companies who are?
Which brand and why?
What they being used for?
Transphorm
- Only 600/650V, only cascode (silicon fet in series with higher voltage depletion GAN)
- Cascode means gate drive is really driving a silicon fet -> easy
- Standard packages (TO-220, TO-247, PQFN)
- Standard gate drive + standard packages make this the easiest to try
- Available on digikey
GAN Systems
- 100V/650V enhancement mode
- Custom but straightforward packages, top side or PCB cooling (10W is realistic)
- Medium difficulty gate drive - wants 6V max is 10V
- Available on mouser
EPC
- 20-200V with a couple 200-300V devices, enhancement mode
- Tiny specialized packages, only PCB based cooling possible (probably ~5W or less)
- Tricky gate drive, wants 5V, but absolute max is 6V
- Perhaps the most established?
- Dozens of parts available on digikey
TI
- One 80V part (half bridge) and one 600V part
- Integrated approach, gate drive, regulator and enable fet is all in the same package
- 80V part available on digikey, 600V part is in 'preview'
On Semi
- Rebrands transphorm?
Infineon
- Has some parts, keeps them secret for now
