SFR9110TF-VB Product details
Back to previous pageProduct introduction：
The SFR9110TF-VB is a Single P-MOSFET deeply optimized for high-voltage negative power rails and power switching applications. The Trench technology achieves a good balance between switching speed and reliability. The TO252 (DPAK) package balances heat dissipation capability with ease of surface mounting. The combination of -100V voltage rating, -8.8A current capability, and 250mΩ on-resistance makes it a reliable alternative to traditional DPAK-packaged P-channel devices, especially suitable for applications with specific requirements for negative voltage control, load switching, and battery reverse polarity protection.
