Electric Vehicle Battery Packs Drive Automotive Qualification Demand
Electric vehicle battery pack designs increasingly specify AEC-Q101 automotive-qualified dual P-channel MOSFETs for cell balancing and protection circuits, since automotive reliability standards require extended temperature cycling and vibration testing that consumer-grade devices do not undergo. Diodes Incorporated and onsemi have both expanded automotive-qualified product lines considerably to serve this growing specification requirement. This shift matters because automotive qualification testing takes considerably longer and costs more than consumer-grade device certification, creating a genuine barrier that has kept several smaller suppliers confined to consumer electronics sockets while larger, better-capitalized suppliers capture the fastest-growing automotive volume reflecting sustained investment.
