800 V: From Automotive Innovation to AI Infrastructure

The move to 800 V electrical architectures began in automotive as a technology challenge: higher system voltages promised greater efficiency, but required semiconductors capable of reliably handling increased electrical and thermal stress.This is where Diotec steps in.

Bringing 800 V from concept to production required years of component qualification. Voltage ratings alone were not enough. Devices had to demonstrate robustness, reliability and consistent performance under demanding real-world conditions.

Today, the same engineering challenge is emerging in AI data centres.

As power requirements increase, 800 V architectures are being introduced to improve power-distribution efficiency and reduce current-related losses. But higher system voltage also places greater demands on the semiconductors responsible for switching, rectification and transient protection.

For engineers and technical buyers, component selection therefore goes beyond electrical specifications. Qualification, device robustness, manufacturing consistency and long-term supply reliability are becoming equally important.

This is an area where the automotive industry's experience offers a valuable benchmark.

Diotec is a semiconductor manufacturer supplying automotive-qualified discrete semiconductors, including SiC MOSFETs like the DI170SIC850D7 and TVS diodes like the P6SMB600CA. These technologies address key requirements in high-voltage power systems, from efficient switching to transient-voltage protection.

The application may be changing from electric vehicles to AI infrastructure, but the fundamental requirement remains the same: high-voltage systems depend on semiconductors that are proven to perform reliably at production scale.
