🚀 Why It’s Ideal for Your Projects

• Low on-resistance for high efficiency — With typical RDS(on) in the 20 mΩ range, the IRF4905 minimizes conduction losses when switching high currents.

• High current capacity — Supports large currents (~70 A rating), making it suitable for demanding loads such as motors, solenoids or power rails.

• Compact, through-hole format — The TO-220 package allows easy mounting, heat-sinking and manual assembly, suitable for both prototypes and production boards.
