Power Components for AI Data Centers and Server Racks

Source MOSFETs, GaN and SiC devices, DC-DC converters, gate drivers, eFuses, and high-current connectors for AI servers, 48 V conversion, and rack power.

About Data Center Power and Components

AI racks draw far more power than a conventional server row. GPU, XPU, and AI ASIC boards create fast load steps, high current density, and tight thermal limits, so the power path from the grid to the processor has to be designed as a system.

Most deployments still use 48 V rack distribution, while 800 VDC and ±400 V architectures are being evaluated for higher-power AI halls. Intermediate bus converters sit between the rack bus and the point-of-load stages that feed CPUs and accelerators.

Octatronics helps engineering and procurement teams source the semiconductors, power ICs, protection devices, and connectors used in that chain — including allocated, NRND, and second-source parts — without changing this page URL or the rest of the application map.

Supply Chain Considerations

!

Lifecycle and allocation

Long-life designs need current lifecycle status, last-time-buy windows, and a documented second source before a line goes NRND.

!

Lead time and date code

We check stock, factory lead time, date code, and packaging so buyers can accept or reject lots before they move.

!

Traceability

COC, photos, and manufacturer traceability are available on request for qualified and high-reliability programs.

Frequently Asked Questions

AI accelerators draw more current and change load faster, so IBC, VRM, thermal, and protection devices have to be sized for that profile.

Not every rack does. Many systems still use 48 V. 800 VDC matters when rack power and copper losses make a higher bus worthwhile.

MPN, quantity, target date code, and whether you need a second source or only the listed manufacturer.

Yes. Hard-to-find MOSFETs, controllers, and connectors are a core sourcing path from this application.
