Fairchild Semiconductor Expands PowerTrench MOSFET Family

August 15, 2012 by Jeff Shepard

Fairchild Semiconductor announced the expansion of the PowerTrench® MOSFET family. Part of the mid-voltage power MOSFET portfolio, these devices are optimized power switches that combine a small gate charge (QG), a small reverse recovery charge (Qrr) and a soft-reverse recovery body diode, allowing for fast switching speeds. Available in a 40, 60 and 80V rating, these devices require less power dissipation in the snubber circuitry due to an optimized soft-body diode that the company says reduces voltage spikes by up to 15 percent over the competitor’s solution.

Employing a shielded-gate silicon technology that provides charge balance, the devices achieve higher power density, low ringing and better light-load efficiency. By using this technology, the devices achieve a lower figure of merit (QG x RDS(ON)) while reducing driving loss to increase power efficiency.

The first devices available include the 40V FDMS015N04B and 80V FDMS039N08B available in a Power56 package, and the 60V FDP020N06B and 80V FDP027N08B available in a TO-220 3-lead package.

The units are priced (in 1,000 quantity pieces) as follows: FDMS015N04B at $1.78; FDMS039N08B at $1.60; at FDP020N06B at $4.50; and FDP027N08B at $3.30; with a delivery of 8-12 weeks ARO.
