FDS Series Dual MOSFET IC — SOP-8, FDS4559 / FDS9926A / FDS4935A / FDS6930B (5-Pack)

FDS Series Dual MOSFET IC — SOP-8 (5-Pack)

The FDS series from onsemi (formerly Fairchild) are dual MOSFET ICs in SOP-8 package, widely used in laptop power management, battery protection circuits, motor drivers, and SMPS designs. Each SOP-8 package contains two MOSFETs in complementary or same-type configurations, making them ideal for synchronous rectification, H-bridge, and load switch applications.
