FDS9945-VB Product details
Back to previous pageProduct introduction：
Troubled by the large board space and high conduction losses of dual-channel power switches? Let the VBsemi FDS9945-VB help! This SOP8-packaged dual N+N channel MOS transistor integrates two independent N-MOSFETs. The 60V withstand voltage provides ample margin, and the 4A continuous current capability confidently handles common power and load management scenarios. The Trench process delivers low on-resistance and fast switching characteristics. The 110mΩ @ 10V on-resistance effectively reduces conduction losses, making it the 'dual-channel efficiency tool' for applications like power conversion and battery protection.
