If adequate heat sinking is provided, they can deliver over 1.0A output current. They are intended as fixed voltage regulators in a wide range of applications including local (on-card) regulation for elimination of noise and distribution problems associated with single-point regulation. In addition to use as fixed voltage regulators, these devices can be used with external components to obtain adjustable output voltages and currents.\u003c\/div\u003e\n\u003cdiv\u003eConsiderable effort was expended to make the entire series of regulators easy to use and minimize the number of external components.

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\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\n\u003ch2\u003e\u003cb\u003ePin Configuration:\u003c\/b\u003e\u003c\/h2\u003e\n\u003ctable border=\"1\" cellspacing=\"0\" cellpadding=\"0\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eNumber\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003e Name\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eDescription\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003ctd\u003eSource\u003c\/td\u003e\n\u003ctd\u003eCurrent flows out through Source (maximum 8A)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2\u003c\/td\u003e\n\u003ctd\u003eGate\u003c\/td\u003e\n\u003ctd\u003eControls the biasing of the MOSFET (Threshold voltage 10V)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e3\u003c\/td\u003e\n\u003ctd\u003eDrain\u003c\/td\u003e\n\u003ctd\u003eCurrent flows in through Drain\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eN-Channel Power MOSFET\u003c\/li\u003e\n\u003cli\u003eContinuous Drain Current (ID): 8A\u003c\/li\u003e\n\u003cli\u003eGate threshold voltage (VGS-th) is 10V (limit = ±20V)\u003c\/li\u003e\n\u003cli\u003eDrain to Source Breakdown Voltage: 500V\u003c\/li\u003e\n\u003cli\u003eDrain-Source Resistance (RDS) is 0.85 Ohms\u003c\/li\u003e\n\u003cli\u003eRise time and the fall time is 23nS and 20nS\u003c\/li\u003e\n\u003cli\u003eAvailable in To-220 package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cb\u003eApplications:\u003c\/b\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eSwitching high power devices\u003c\/li\u003e\n\u003cli\u003eInverter Circuits\u003c\/li\u003e\n\u003cli\u003eDC-DC Converters\u003c\/li\u003e\n\u003cli\u003eControl speed of motors\u003c\/li\u003e\n\u003cli\u003eLED dimmers or flashers\u003c\/li\u003e\n\u003cli\u003eHigh-Speed switching applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cb\u003eDatasheet:\u003cbr\u003e\n\u003ca href=\"https:\/\/www.flyrobo.in\/download\/IRF840-Datasheet-FR452.pdf\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eDownload\u003c\/a\u003e\u003c\/b\u003e\u003c\/h2\u003e\n\u003ch2\u003e\u003cb\u003ePackage Includes:\u003c\/b\u003e\u003c\/h2\u003e\n\u003cp\u003e1 x IRF840 N-channel 8A 500V Power MOSFET\u003c\/p\u003e\n\u003ch6\u003e\u003cspan style=\"color: #ffffff;\"\u003e\u003ca style=\"color: #ffffff;\" href=\"https:\/\/www.amazon.com\/Brands-IRF840-Transistor-MOSFET-Channel\/dp\/B01N26Q6N0\/ref=sr_1_2?dchild=1\u0026amp;keywords=IRF840+N-channel+8A+500V\u0026amp;qid=1604147552\u0026amp;sr=8-2\"\u003e focus keyphrase\u003c\/a\u003e \u003c\/span\u003e\u003c\/h6\u003e\n\u003c\/div\u003e","brand":"Electronics Hub","offers":[{"title":"Default Title","offer_id":54466802811193,"sku":"product-6254","price":80.0,"currency_code":"PKR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0965\/3623\/2249\/files\/s-l300-2-2.jpg?v=1789233488"},{"product_id":"l7810-voltage-regulator-in-pakistan","title":"L7810 voltage regulator in Pakistan","description":"\u003ch3 id=\"description\" class=\"tab-list-title\"\u003eDescription\u003c\/h3\u003e\n\u003cdiv id=\"content_description\" class=\"ty-wysiwyg-content content-description\"\u003e\n\u003cdiv\u003e\n\u003cp\u003eThe L7810 voltage regulator of three-terminal positive regulators is available in TO-220,\u003cbr\u003e\nTO-220FP, D²PAK and DPAK packages and several fixed output voltages, making it\u003cbr\u003e\nuseful in a wide range of applications.\u003cbr\u003e\nThese regulators can provide local on-card regulation, eliminating the distribution\u003cbr\u003e\nproblems associated with single point regulation.
