When the device is being used for switching inductive loads like a transformer or a motor, a flyback diode should be normally connected across the load, with the cathode of the diode connected to the positive side of the load. If the trigger input is not a logic source make sure the gate is permanently connected to ground via a high value resistor. The drain should be connected to the positive terminal of the supply via the load which needs to be operated by the device.įinally, the gate which is the trigger lead of the device should be connected to the trigger point of the circuit, this trigger input should be preferably a +5V supply from a CMOS logic source. The source should be preferably connected to the ground or the negative line of the supply.

It’s quite simple, and must be done as explained in the following points: This device is best suited for high power DC switching applications, such as in high current SMPS power supplies, compact ferrite inverter circuits, iron core inverter circuits, buck and boost converters, power amplifiers, motor sped controllers, robotics etc. V (BR)DSS= 100 volts, It’s the maximum voltage that may be applied across drain to source of the device. It’s the maximum trigger voltage that may be applied across the gate and the source for optimal performance. P D = 130 Watts Max, The maximum power the FET can dissipate with and infinite (cool) heat sink I DM = 110 Amps Max, It’s the maximum current handling capacity of the device across the drain to the source, via the load, in a pulsed mode (NOT continuous). I D = 33 Amps Max at 10V (V GS), It’s the maximum current handling capacity of the device across the drain to the source, via the load, with gate voltage at 10V, at normal temperatures (25 to 35 degrees Cel.) Maximum tolerable limits of IRF540N are stated as under:

Fully resistant against avalanche or peak surge currents.

Operating temperature tolerance capacity as high as 175 degrees Celsius.

Extremely low resistance across load path.Sophisticated, cutting-edge processing technology used.
