FDB3632-F085-VB Product details
Back to previous pageProduct introduction：
The FDB3632-F085-VB is a Single N-MOSFET deeply optimized for high-voltage, high-current power switch scenarios. The Trench process balances ultra-low conduction loss and high switching speed. The TO263 package achieves a balance between heat dissipation capability and ease of installation. The combination of 100V voltage rating, 140A current capability, and 4mΩ on-resistance makes it an ideal upgrade option to replace traditional DPAK or D2PAK packaged devices, especially suitable for high-power-density, high-reliability automotive and industrial applications.
