NXP Announces New Range Of Small Signal MOSFETs At APEC 2008
NXP Semiconductors announced a new range of small signal MOSFET devices housed in what is described as one of the world’s smallest packages, the SOT883. Boasting an ultra-small 1.0 x 0.6mm footprint, NXP’s SOT883 MOSFETs are said to deliver power dissipation and performance comparable to SOT23, while occupying only 14% of the printed circuit board space.
Designed for use in a broad range of applications including dc-dc converter modules, power supplies for LCD TV and load switching for mobile phones and other portable devices, the SOT883 MOSFETs’ ultra-small footprint, extremely low 0.5 mm profile and what is described as best-in-class switching speed and very low Rds(on) enable manufacturers to meet consumer demand for more compact and power-efficient products.
"Market demands for smaller portable devices with increased battery life are driving the race to fit sophisticated functionality into smaller and smaller form factors," said Dean Montano, Product Marketing Manager, NXP Semiconductors. "Built on NXP’s proven Quad Flat Non-leaded technology, the SOT883 MOSFETs offer customers a power efficient and environmentally friendly package that still delivers the performance required by today’s cellular phone and mobile computing applications."
In addition to dramatically reducing the MOSFETs’ footprint, NXP has eliminated the leads, which both frees up additional board space and improves thermal performance. This combination of thermal performance and Rds(on) values of less than 0.65Ω at 2.5V is said to allow NXP’s newest MOSFETs to offer higher current carry capacity than currently available 1.0 x 0.6mm MOSFETs. The new series also features what is described as best in class switching speed, with turn on times between 12-16ns and turn-off times between 17-24ns.
Manufactured using pure tin plating, high-efficiency packing techniques and green plastics that dispense with toxic flame retardants, the SOT883 MOSFET devices meet all environmental protection targets. The high packing density also fits 10,000 devices on a standard 180mm reel, thus lowering assembly costs and inventory requirements.
Pricing starts at US $0.20 for delivery in quantities of 10K MOQ.
