Novel package keeps MOSFETs cooler
A new family of TrenchFET power MOSFETs come in novel reverse-lead TO-252 DPAK packages.

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.
Because heat generated from power can be dissipated to the air rather than to the PCB, each of these power mosfets features a lower effective on-resistance value and higher current capability than DPAK power mosfets with conventional lead-outs.
Cooler operation also takes thermal stress off the board, contributing to better overall reliability.
Used for desktop computer core DC/DC conversion applications, the SUR power mosfets enable the design of "greener" VRM modules and PC motherboards that use power more efficiently and require fewer components.
The 20V SUR70N02 04P and 30V SUR50N03 06P, SUR50N03 09P, SUR50N03 12P, and SUR50N03 16P power mosfets offer a range of on-resistance values from 4 to 16mohm and can serve as both synchronous and control FETs in DC/DC convertors.
Samples and production quantities of the SUR family reverse-lead TrenchFET power mosfets are available now, with lead times of 10 to 12 weeks for larger orders.
Pricing for US delivery starts at $0.60 in 100,000-piece quantities.
