SFT1341-C-TL-W-VB Product details
Back to previous pageProduct introduction：
SFT1341-C-TL-W-VB is a Single P-MOS optimized for low-voltage power switching scenarios. The Trench process balances low switching loss with high reliability, and the TO252 package achieves a good balance between heat dissipation and mounting convenience. The combination of -40V withstand voltage, -40A current carrying capacity, and 17mΩ on-resistance makes it an ideal choice for high-power-density power management, battery protection, and motor drive applications, especially suitable for industrial-grade and automotive-grade projects requiring high current and low loss.
