Next-generation PowerTrench MOSFETs claim best-in-class performance
The FDMS86181 is the first part in Fairchild’s new generation of PowerTrench MOSFETs and the device claims to deliver improvements in efficiency, reduced voltage ringing and lower electromagnetic interference (EMI) for power supplies, motor drives and other applications requiring a 100 V MOSFET.
The primary advantages of the FDMS86181 are its 40 percent reduction in Rdson which lowers conduction losses and its minimized gate charge (Qg) which reduces switching losses. The low Qrr of the FDMS86181 virtually eliminates the voltage overshoots that cause ringing, which allows for the reduction or elimination of snubbers in product designs and reduces EMI. This unique advantage of the FDMS86181 allows designers to both reduce product size and bill-of-materials (BOM) costs.
