In High Power Applications, such as Motor Control, one MOSFET may not be enough – hence paralleling MOSFETs becomes a necessary solution. To achieve a reliable design that shares and stresses the devices equally, it is common to request semiconductor manufacturers to provide parts with matched threshold voltages. However, even with very tightly controlled production facilities there is an inevitable spread in the threshold voltage across the wafer. Any effort to provide matched Vth will require special screening and sorting that can result in yield loss, thus affecting the cost of the devices supplied. Nexperia have developed a new and unique MOSFET with improved current sharing capability when used in parallel which no longer relies on matched threshold voltages.
