Working Principle of IRF510 MOSFET

The IRF510 operates as an N-Channel enhancement MOSFET, meaning it remains OFF until a sufficient positive voltage is applied at the gate relative to the source. When VGS exceeds the threshold voltage, a conductive channel forms between the drain and source, allowing current to flow. This makes the IRF510 ideal for switching, amplification, and modulation tasks. In analog applications such as RF amplifiers, the MOSFET functions in its linear region, delivering smooth signal amplification with good frequency response.
