The Mosfet could switch loads that consume up to 8A, it can turn on by providing a gate threshold voltage of 10V across the Gate and Source pin. Since the MOSFET is for switching high current high voltage loads it has a relatively high gate voltage, hence cannot be used directly with an I\/O pin of a CPU. If you prefer a mosfet with low gate voltage then try IRF540N or 2N7002 etc.\u003c\/p\u003e\r\n\r\n\u003cp\u003eOne considerable disadvantage of the IRF840 Mosfet is its high on-resistance (RDS) value which is about 0.85 ohms. Hence this mosfet cannot be used in applications where high switching efficiency is required. The Mosfet requires a driver circuit to provide 10V to the gate pin of this Mosfet the simplest driver circuit can be build using a transistor. It is relatively cheap and has very low thermal resistance, added to this the mosfet also has good switching speeds and hence can be used in DC-DC converter circuits.\u003c\/p\u003e\r\n\r\n\u003ch2\u003e\u003cb\u003ePin Configuration:\u003c\/b\u003e\u003c\/h2\u003e\r\n\r\n\u003ctable border=\"1\" cellpadding=\"0\" cellspacing=\"0\"\u003e\r\n\t\u003ctbody\u003e\r\n\t\t\u003ctr\u003e\r\n\t\t\t\u003ctd\u003e\r\n\t\t\t\u003cp\u003e\u003cstrong\u003ePin Number\u003c\/strong\u003e\u003c\/p\u003e\r\n\t\t\t\u003c\/td\u003e\r\n\t\t\t\u003ctd\u003e\r\n\t\t\t\u003cp\u003e\u003cstrong\u003ePin\u003c\/strong\u003e\u003cstrong\u003e Name\u003c\/strong\u003e\u003c\/p\u003e\r\n\t\t\t\u003c\/td\u003e\r\n\t\t\t\u003ctd\u003e\r\n\t\t\t\u003cp\u003e\u003cstrong\u003eDescription\u003c\/strong\u003e\u003c\/p\u003e\r\n\t\t\t\u003c\/td\u003e\r\n\t\t\u003c\/tr\u003e\r\n\t\t\u003ctr\u003e\r\n\t\t\t\u003ctd\u003e\r\n\t\t\t\u003cp\u003e1\u003c\/p\u003e\r\n\t\t\t\u003c\/td\u003e\r\n\t\t\t\u003ctd\u003e\r\n\t\t\t\u003cp\u003eSource\u003c\/p\u003e\r\n\t\t\t\u003c\/td\u003e\r\n\t\t\t\u003ctd\u003e\r\n\t\t\t\u003cp\u003eCurrent flows out through Source (maximum 8A)\u003c\/p\u003e\r\n\t\t\t\u003c\/td\u003e\r\n\t\t\u003c\/tr\u003e\r\n\t\t\u003ctr\u003e\r\n\t\t\t\u003ctd\u003e\r\n\t\t\t\u003cp\u003e2\u003c\/p\u003e\r\n\t\t\t\u003c\/td\u003e\r\n\t\t\t\u003ctd\u003e\r\n\t\t\t\u003cp\u003eGate\u003c\/p\u003e\r\n\t\t\t\u003c\/td\u003e\r\n\t\t\t\u003ctd\u003e\r\n\t\t\t\u003cp\u003eControls the biasing of the MOSFET (Threshold voltage 10V)\u003c\/p\u003e\r\n\t\t\t\u003c\/td\u003e\r\n\t\t\u003c\/tr\u003e\r\n\t\t\u003ctr\u003e\r\n\t\t\t\u003ctd\u003e\r\n\t\t\t\u003cp\u003e3\u003c\/p\u003e\r\n\t\t\t\u003c\/td\u003e\r\n\t\t\t\u003ctd\u003e\r\n\t\t\t\u003cp\u003eDrain\u003c\/p\u003e\r\n\t\t\t\u003c\/td\u003e\r\n\t\t\t\u003ctd\u003e\r\n\t\t\t\u003cp\u003eCurrent flows in through Drain\u003c\/p\u003e\r\n\t\t\t\u003c\/td\u003e\r\n\t\t\u003c\/tr\u003e\r\n\t\u003c\/tbody\u003e\r\n\u003c\/table\u003e\r\n\r\n\u003ch2\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/h2\u003e\r\n\r\n\u003cul\u003e\r\n\t\u003cli\u003eN-Channel Power MOSFET\u003c\/li\u003e\r\n\t\u003cli\u003eContinuous Drain Current (ID): 8A\u003c\/li\u003e\r\n\t\u003cli\u003eGate threshold voltage (VGS-th) is 10V (limit = ±20V)\u003c\/li\u003e\r\n\t\u003cli\u003eDrain to Source Breakdown Voltage: 500V\u003c\/li\u003e\r\n\t\u003cli\u003eDrain-Source Resistance (RDS) is 0.85 Ohms\u003c\/li\u003e\r\n\t\u003cli\u003eRise time and the fall time is 23nS and 20nS\u003c\/li\u003e\r\n\t\u003cli\u003eAvailable in To-220 package\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\r\n\u003ch2\u003e\u003cb\u003eApplications:\u003c\/b\u003e\u003c\/h2\u003e\r\n\r\n\u003cul\u003e\r\n\t\u003cli\u003eSwitching high power devices\u003c\/li\u003e\r\n\t\u003cli\u003eInverter Circuits\u003c\/li\u003e\r\n\t\u003cli\u003eDC-DC Converters\u003c\/li\u003e\r\n\t\u003cli\u003eControl speed of motors\u003c\/li\u003e\r\n\t\u003cli\u003eLED dimmers or flashers\u003c\/li\u003e\r\n\t\u003cli\u003eHigh-Speed switching applications\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\r\n\u003ch2\u003e\u003cb\u003eDatasheet:\u003cbr\u003e\r\n\u003ca href=\"https:\/\/www.flyrobo.in\/download\/IRF840-Datasheet-FR452.pdf\" target=\"_blank\" rel=\"noopener noreferrer\" title=\"Download\" aria-label=\"Visit a webpage about Download\"\u003eDownload\u003c\/a\u003e\u003c\/b\u003e\u003c\/h2\u003e\r\n\r\n\u003ch2\u003e\u003cb\u003ePackage Includes:\u003c\/b\u003e\u003c\/h2\u003e\r\n\r\n\u003cp\u003e1 x IRF840 N-channel 8A 500V Power MOSFET\u003c\/p\u003e","brand":"Digilog Electronics","offers":[{"title":"Default Title","offer_id":43962385432641,"sku":"B669,L10,Th5","price":100.0,"currency_code":"PKR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0727\/2805\/1777\/files\/irf840-n-channel-8a-500v-power-mosfet-550x550_y7uw-nq.jpg?v=1779570997","url":"https:\/\/stem.pk\/products\/irf840-n-channel-8a-500v-power-mosfet-in-pakistan","provider":"stem.pk","version":"1.0","type":"link"}
