Gallium nitride devices have moved past the consumer charger market and into industrial power conversion. The change matters to procurement teams because the sourcing base is narrower than silicon MOSFETs and the qualification requirements are less standardised.
What is different about sourcing GaN
- Fewer authorised manufacturers, so approved-vendor substitution is riskier.
- Datasheet parameters are less directly comparable across manufacturers than for silicon.
- Application support often sits with the manufacturer rather than the distributor.
Qualification considerations
Programmes moving to GaN should plan for longer engineering validation and confirm the specific device revision, since several manufacturers have made die revisions within the same part number. An authorisation relationship makes revision notification reliable.
Supply outlook
Capacity is being added, but demand is growing faster in server and motor drive applications. Expect allocation to persist on the highest-efficiency grades through 2027.
