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.<\/p>\n<p>One 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.<\/p>\n<h2><b>Pin Configuration:<\/b><\/h2>\n<table border=\"1\" cellpadding=\"0\" cellspacing=\"0\">\n<tbody>\n<tr>\n<td>\n<p><strong>Pin Number<\/strong><\/p>\n<\/td>\n<td>\n<p><strong>Pin<\/strong><strong>\u00a0Name<\/strong><\/p>\n<\/td>\n<td>\n<p><strong>Description<\/strong><\/p>\n<\/td>\n<\/tr>\n<tr>\n<td>\n<p>1<\/p>\n<\/td>\n<td>\n<p>Source<\/p>\n<\/td>\n<td>\n<p>Current flows out through Source (maximum 8A)<\/p>\n<\/td>\n<\/tr>\n<tr>\n<td>\n<p>2<\/p>\n<\/td>\n<td>\n<p>Gate<\/p>\n<\/td>\n<td>\n<p>Controls the biasing of the MOSFET (Threshold voltage 10V)<\/p>\n<\/td>\n<\/tr>\n<tr>\n<td>\n<p>3<\/p>\n<\/td>\n<td>\n<p>Drain<\/p>\n<\/td>\n<td>\n<p>Current flows in through Drain<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2><b>Features:<\/b><\/h2>\n<ul>\n<li>N-Channel Power MOSFET<\/li>\n<li>Continuous Drain Current (ID): 8A<\/li>\n<li>Gate threshold voltage (VGS-th) is 10V (limit = \u00b120V)<\/li>\n<li>Drain to Source Breakdown Voltage: 500V<\/li>\n<li>Drain-Source Resistance (RDS) is 0.85 Ohms<\/li>\n<li>Rise time and the fall time is 23nS and 20nS<\/li>\n<li>Available in To-220 package<\/li>\n<\/ul>\n<h2><b>Applications:<\/b><\/h2>\n<ul>\n<li>Switching high power devices<\/li>\n<li>Inverter Circuits<\/li>\n<li>DC-DC Converters<\/li>\n<li>Control speed of motors<\/li>\n<li>LED dimmers or flashers<\/li>\n<li>High-Speed switching applications<\/li>\n<\/ul>\n<h2><b>Datasheet:<br \/>\n<a href=\"https:\/\/www.flyrobo.in\/download\/IRF840-Datasheet-FR452.pdf\" target=\"_blank\" rel=\"noopener noreferrer\" title=\"Download\">Download<\/a><\/b><\/h2>\n<h2><b>Package Includes:<\/b><\/h2>\n<p>1 x\u00a0IRF840 N-channel 8A 500V Power MOSFET<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The IRF840 is an N-Channel Power MOSFET which can switch loads up to 500V.
