Philips has a new generation of small discrete leadless devices packaged using quad flat nonleaded (QFN) technology. The new SOT88x package family provides designers of space-constrained applications an excellent choice for optimising system performance in terms of PCB area and height while adding "discrete" functionality in a true mass production package. The high performance and extremely small size of the SOT88x family make it ideal for applications such as LCD backlight related devices, DC/DC conversion, ESD protection devices and small-signal switching transistors.
Power dissipation and board space are critical factors in the design of many embedded systems today.
With dimensions of 1.0 x 0.6 x 0.5mm and bottom contact pads, the new SOD882 and SOT883 packages feature one of the smallest board space requirements in the industry, while offering outstanding power dissipation capability comparable to the industry standard SOT23.
The best-in-class power dissipation is based on the heat-transfer capabilities of the leadless layout.
As a result, customers benefit from the latest in miniaturisation without any compromise in the electrical specification.
"Leveraging our expertise in discrete package solutions and technologies such as QFN, we have designed these new packages to enable designers to achieve the maximum amount of functionality in handheld applications such as mobile phones, PDAs, notebook PCs, portable DVD players and optical disc drives", said Jorgen Lange, Senior Director Marketing for small-signal discretes at Philips Semiconductors "Philips offers one of the broadest portfolios of packaging options in the industry to meet virtually any customer design need".
Philips is offering a wide range of discrete semiconductors in the new leadless SOD882 and SOT883 packages including mosfets, general purpose transistors, resistor equipped transistors, Low-saturation-voltage BISS transistors, wideband transistors, switching diodes, Zener diodes Schottky-barrier diodes, varicap diodes, bandswitch diodes and PIN diodes.
All products in SOD882 and SOT883 are packed in very thin paper tape combined with a product pitch of 2mm.
This combination enables Philips to offer 10,000 products on standard 180mm reel while reducing the effort needed to change the reels on a pick-and-place machine to less than three times that of other products (compared with 3000 SOT23 products on a 180mm reel).
Devices released in the new SOD882 and SOT883 packages are currently available in volume.
