Across the last several weekly market scans, one pattern keeps repeating: automotive-qualified power and isolation devices are pulling away from the rest of the semiconductor market in both search volume and price momentum.

High-side power switches, motor drivers, isolated interface ICs, and precision voltage references used in body electronics, motor control, and battery-management systems are showing triple-digit percentage increases in buyer search activity week over week — even while commodity MOSFETs and mature regulators in the same broad categories continue to see aggressive price compression.

What this means for buyers:

• Automotive-qualified (AEC-Q100/Q101) power and isolation parts should be treated as allocation-sensitive, not general-purpose stock.
• Isolated gate drivers, isolated ADCs, and digital isolators paired with integrated isolated power are increasingly bottleneck items as power density rises across EV, industrial automation, and factory equipment.
• Connector terminals and socket connectors are emerging as a secondary risk — a production line can stop over one terminal just as easily as one chip.

Cerametronics’ sourcing team is actively tracking allocation status on the automotive power and isolation families most exposed to this shift. If any of these categories sit in your BOM, we recommend a proactive stock and lead-time check rather than waiting for a shortage notice.
