WebThis generates substantial heat requiring proper thermal management in the form of heat sinks. FETs also are not typically designed for 100s of amps on their own, so a typical FET-based design will require many FETs in parallel to handle the power (in some cases I've seen 6-10 on a single board). WebNote that, in parallel-connected MOSFETs (as used in the internal structure of the HEXFET and L-MOSFET devices described above), equal current sharing is ensured by the conduction channel’s positive temperature coefficient; if the current in one MOSFET becomes excessive, the resultant heating of its channel raises its resistance, thus … makita avt reciprocating sawWebEach additional parallel MOSFET added to a circuit improves the voltage drop, power loss, and accompanying temperature rise of the application. But, the parallel MOSFETs do not necessarily improve the transient power capability of the circuit. makita auto feed screws
