FQB19N10LTM-VB Product details
Back to previous pageProduct introduction：
FQB19N10LTM-VB is a Single N-MOS optimized for medium-voltage power switching scenarios. The Trench process balances low switching losses and high reliability, while the TO263 package achieves a good balance between heat dissipation and current carrying capacity. The combination of 100V withstand voltage, 20A current capability, and 100mΩ on-resistance makes it an ideal upgrade option to replace traditional TO220 or DPAK package devices, especially suitable for industrial and automotive applications requiring large heat dissipation areas and high reliability.
