What to research

Build a company map, not a logo wall.

For each manufacturer, look for technology family, voltage range, package platform, qualification, application notes, SPICE models, lifetime status and distributor availability.

Technology families

CoolMOS, MDmesh, DTMOS, Super J-MOS, EF, NextPower and other proprietary naming systems are brand/product families—not generic replacements for the term superjunction.

Application positioning

AI/server power, EV charging, renewable power conversion, telecom and industrial systems are major demand signals for higher efficiency and power density.

Official evidence

Manufacturer pages are useful for current portfolios and product claims. Independent papers should be used for scientific context and comparative analysis.
