MOSFET's merit means lower losses
N-channel power MOSFET claims record-breaking specifications for on-resistance and figure of merit.
The first device in a new third-generation TrenchFET power MOSFET family offering record-breaking specifications for on-resistance and on-resistance times gate charge has been released by Vishay Intertechnology The new TrenchFET Gen III Si7192DP, an N-channel device in the PowerPAK SO-8 package, features maximum on-resistance of 2.25mohm at a 4.5V gate drive voltage

Novel power package reduces MOSFET on-resistance
Siliconix has released 14 industry-leading PowerPAK power MOSFETs featuring improved package technology that yields lower on-resistance devices.
Drivers integrate MOSFETs with drive circuitry
Five new Little Foot Plus driver products are designed to simplify the use of N-channel MOSFETs in high-frequency buck regulators.
On-resistance times gate charge, a key figure of merit (FOM) for MOSFETs in DC/DC convertor applications, is 98 - a new industry record for any VDS = 30V, VGS = 20V device in an SO-8 footprint.
Compared with the closest competing devices optimised for low conduction losses and low switching losses, these represent the best available specifications on the market.
Lower on-resistance and lower gate charge translate into lower conduction and switching losses, respectively.
The Vishay Siliconix Si7192DP will be used as the low-side MOSFET in synchronous buck convertors and in secondary synchronous rectification and ORing applications.
Its low conduction and switching losses will enable more power-efficient and space-efficient designs for voltage regulator modules (VRMs), servers and a wide range of systems using point-of-load (POL) power conversion.
Vishay Siliconix was the industry's first supplier to introduce trench power MOSFETs.
The company's TrenchFET IP includes numerous patents, including fundamental technology patents dating from the early 1980s.
Each new generation of TrenchFET technology yields products that raise the bar for power MOSFET performance in a wide range of computing, communications, consumer electronics, and many other applications.
Samples and production quantities of the Si7192DP are available now, with lead times of 10 to 12 weeks for large orders.
Pricing for US delivery in 100,000-piece quantities is $0.85.
