The IRF540 transistor is an N-channel MOSFET, which means that no current will flow between the drain and source leads when no voltage is applied to the transistor&#8217;s gate. On the other hand, when a voltage exceeding a threshold value is applied to the transistor&#8217;s gate, the drain-source circuit will be closed and electric current will flow through it.    <\/p>\n<p>Since it is an N-channel transistor, the load circuit controlled by it should always be <strong>connected above the lead<\/strong>. When we turn on a MOSFET transistor by supplying the appropriate voltage to its gate, it will be on all the time and will conduct until a zero voltage appears back at the gate. To avoid this problem, we should always connect <a href=\"https:\/\/botland.com.pl\/50-rezystory-oporniki\" target=\"_blank\" rel=\"noopener\" data-wpel-link=\"internal\">a<\/a> pull-down <a href=\"https:\/\/botland.com.pl\/50-rezystory-oporniki\" target=\"_blank\" rel=\"noopener\" data-wpel-link=\"internal\">resistor<\/a> to ground between the gate and the source. In applications such as controlling the speed of electric motors or controlling the dimming of lights, we should use a<strong> PWM signal<\/strong> to control the MOSFET transistor. Here we should bear in mind that then the gate capacitance of the MOSFET transistor can create conditions for reverse current flow. For this reason, we should use an additional resistor R2, which effectively nullifies the effect of the capacitive effect of the transistor&#8217;s gate.     <\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-f9c3ca7 elementor-widget elementor-widget-heading\" data-id=\"f9c3ca7\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Connection of the IRF540 transistor<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-968ad31 elementor-widget elementor-widget-text-editor\" data-id=\"968ad31\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>First, connect the source pin to ground or the negative rail of the supply voltage. The drain should be connected to the positive rail of the supply voltage, through the load whose switching on and off you want to control. The gate, or control electrode, is connected to the trigger source. The preferred trigger source for the gate <strong>should give a voltage of 5 V<\/strong>, according to the TTL technology standard. If the trigger source is not a logic circuit or microcontroller, make sure that the gate of the transistor is connected to ground through a resistor. If our transistor is to be used to switch inductive loads, such as transformers or<a href=\"https:\/\/botland.com.pl\/5-silniki\" target=\"_blank\" rel=\"noopener\" data-wpel-link=\"internal\"> motors<\/a>, we should connect an overvoltage protection diode in parallel to the load. We connect its cathode to the positive rail of the supply voltage, and its anode to the drain of the transistor. In this way, we will protect the transistor from damage due to overvoltages resulting from switching off circuits with inductances.       <\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-5dd60ba elementor-widget elementor-widget-heading\" data-id=\"5dd60ba\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Index N in the designation<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-0c8082a elementor-widget elementor-widget-text-editor\" data-id=\"0c8082a\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>When selecting <a href=\"https:\/\/botland.com.pl\/91-tranzystory-unipolarne-mosfet\" target=\"_blank\" rel=\"noopener\" data-wpel-link=\"internal\">a MOSFET trans<\/a> istor for our application, it is worth paying attention to additional indices in the naming in addition to its basic name, and this also applies to the IRF540 transistor discussed in the following article.

In contrast, the IRF540N transistor, note the subscript &#8220;N&#8221; in its name, is made using planar technology, which uses a larger area of the silicon wafer, thus achieving <strong>higher current throughput<\/strong>. What also distinguishes the IRF540N from its counterpart without the &#8220;N&#8221; in the designation is the lower maximum resistance of the drain-source junction in the ON state, which is 44 m\u03a9, while for the IRF540 it is only 77 m\u03a9. The difference in the maximum conduction current is also important, for the IRF540 it is 23 A, while for the IRF540N it is 33 A, but these values can vary depending on the specifications of the specific component manufacturer.    <\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-adb5eaa elementor-widget elementor-widget-heading\" data-id=\"adb5eaa\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">IRF540 - replacements<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-a6af9df elementor-widget elementor-widget-text-editor\" data-id=\"a6af9df\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Replacements for the IRF540 transistor are commercially available, which are similar with respect to each other in the most important parameters, although they may have <strong>a different pinout and type of housing<\/strong>, which should be taken into account in the design of electronic devices as well as in the assembly process.
