Pchannel mosfet absolute maximum ratings ta 25 c unless otherwise noted parameter symbol 10 secs steady state unit drainsource voltage vds. Power mosfet basics understanding voltage ratings application note an851. Since the transistor current is proportional to the gate overdrive vgvt, high performance demands have dictated the use of higher supply voltage. The irf540n is a great mosfet to start turning bigger loads on and off. This is one of the most complicated but important figure that should not be ignored in the datasheet. The mosfet uses infineon 800v c3 coolmos advanced technology to deliver high performance with low rdson and fast switching in a low ohmic hermetic package. Mosfet which has become the most commonly used three terminal devices brings revolution in the world of electronic circuits. You will use the mosfet as a variable resistor and as a switch. When the lowside mosfet turns off, the voltage at lgate pin is sensed. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Note that the values given in the data sheet table have conditions associated with them.
