![]() ![]() Since the mosfet is for switching high current high voltage loads it has a relatively high gate voltage, hence cannot be used directly with a I/O pin of a CPU. The Mosfet could switch loads that consume upto 8A, it can turned on by providing a gate threshold voltage of 10V across the Gate and Source pin. The IRF840 is an N-Channel Power MOSFET which can switch loads upto 500V. Note: Complete technical details can be found at the IRF840 datasheet linked at the bottom of the page Rise time and fall time is 23nS and 20nS.Drain Source Resistance (RDS) is 0.85 Ohms. ![]() Gate threshold voltage (VGS-th) is 10V (limit = ☒0V).The Mosfet could switch loads that consume upto 8A, it can turned on by providing a gate threshold voltage of 10V across the Gate and Source pin.Ĭurrent flows out through Source (maximum 8A)Ĭontrols the biasing of the MOSFET (Threshold voltage 10V)
