IRF630N N-MOSFET 200V 9.3A

The IRF630N is a versatile N-channel power MOSFET designed for high-voltage switching and amplification applications. Built into the rugged TO-220 through-hole package , this MOSFET delivers reliable performance and is easy to mount on standard heatsinks for sustained operation under load. With a maximum drain-source voltage of 200V and a continuous drain current rating of 9.3A , the IRF630N is particularly well suited for high-voltage circuits where standard 100V MOSFETs fall short — such as mains-rectified power supplies, off-line converters, fluorescent ballasts, induction heaters, and high-voltage motor drives . Its 82W power dissipation rating allows it to handle continuous high-power switching when properly heatsinked. The transistor's low on-resistance of 0.30? (300 m?) keeps conduction losses minimal during operation, while its fast switching characteristics make it suitable for high-frequency PWM applications including switch-mode power supplies (SMPS), DC-DC converters, and inverters . Its high voltage rating provides excellent margin in 110V and 220V mains-derived circuits. Note on gate drive: The IRF630N is not a logic-level MOSFET and typically requires a gate-source voltage of around 10V for full enhancement. To switch the IRF630N from a 5V Arduino or 3.3V microcontroller, use a dedicated MOSFET gate driver IC or a transistor-based driver stage to provide the proper gate voltage.
