Fairchild 100V MOSFET Provides 50% Lower RDS(ON) For Power Supply Designs
Fairchild Semiconductor states that it is providing designers of isolated dc-dc applications a 100V MOSFET with 50% lower RDS(ON) and excellent FOM for higher efficiency in power supply designs. The FDMS86101, a 100V MOSFET packaged in 5 x 6mm MLP Power56 packaging, is designed using Fairchild’s PowerTrench® process that minimizes on-state resistance, while maintaining what is described as superior switching performance and ruggedness.
This proprietary process technology is said to provide the industry’s lowest RDS(ON) (8mΩ) compared to current solutions with the same gate charge and allows the FDMS86101 to improve conduction losses without suffering the penalty of a higher gate charge. Ethernet, blade servers and telecom applications are transitioning from a 12 to a 48V power supply and the need for switches that optimize efficiency is increasingly important.
This PowerTrench MOSFET offers a built-in enhanced soft-body diode that lowers switching noise and decreases the applications’ susceptibility to EMI. According to Fairchild, this feature saves board space and reduces components because many alternate solutions need to include a snubber network to reduce switching noise spikes.
The FDMS86101 is part of a comprehensive portfolio of PowerTrench MOSFETs that are described as being instrumental in achieving higher energy efficiency by meeting the electrical and thermal performance requirements for today’s electronics. Fairchild’s advanced-performance PowerTrench MOSFET process technology is said to yield exceptionally low values for Miller Charge (QGD), RDS(on) and total gate charge (QG) – enhancements that result in superior switching performance and thermal efficiencies.
The units are priced (each, 1000 pcs.) at $1.55 with a delivery of 8-10 weeks.
