FQU8P10TU-VB Product details
Back to previous pageProduct introduction：
FQU8P10TU-VB is a Single P-MOS deeply optimized for medium-to-high voltage power switching scenarios. The Trench process balances low switching loss with high reliability, and the TO251 package achieves a good balance between heat dissipation capability and installation convenience. The combination of -100V withstand voltage, -12A current carrying capacity, and 215mΩ on-resistance makes it an ideal cost-reduction incremental option for replacing traditional DPAK or SOP-8 packaged devices, especially suitable for industrial and consumer applications with clear requirements for voltage margin and heat dissipation.
