Improving power density and light-load efficiency is a key issue for server, telecommunications, and AC-DC power designers. Furthermore, in these switch-mode power supply (SMPS) designs, synchronous rectification functions require cost-effective power supply solutions that can increase efficiency and reduce power consumption while minimizing board space. Fairchild Semiconductor (NYSE: FCS) is supporting designers in meeting these power design technical challenges by expanding its PowerTrench® MOSFET family.
These devices, included in the medium-voltage power MOSFET portfolio, support fast switching speeds as optimized power switches integrating small gate charge (QG), small reverse recovery charge (Qrr), and soft-reverse recovery body diodes. These devices are available in 40V, 60V, and 80V ratings and allow for the use of relatively smaller snubber circuits due to optimized soft-body diodes that reduce voltage spikes by up to 15% compared to competing solutions.
The devices achieve higher power density, lower ringing characteristics, and improved light-load efficiency by employing silicon shielded-gate technology that provides charge balancing capabilities. By using this technology, the devices can increase power efficiency by simultaneously reducing drive losses while achieving a relatively low performance index (QG x RDS(ON)).
The devices to be initially supplied include 40V FDMS015N04B and 80V FDMS039N08B provided in Power56 packages, and 60V FDP020N06B and 80V FDP027N08B provided in TO-220 3-lead packages.

Features and Advantages:
• Miniaturized package sizes (Power56 and TO-220 3-lead) provide maximum temperature performance relative to system size.
• A relatively low QG reduces gate drive losses.
• A low QGD/QGS ratio that prevents unnecessary turn-on improves system performance.
• Low dynamic parasitic capacitance reduces gate drive losses for high-frequency applications.
• 100% UIL tested
• RoHS compliant
.
Fairchild’s medium-voltage MOSFET products have been enhanced with the addition of these new PowerTrench MOSFETs. The devices are part of the comprehensive PowerTrench technology portfolio and are important for achieving higher energy efficiency by meeting the electrical and thermal performance requirements of modern electronic devices.
