Avago Technologies today introduced the industry's thinnest surface mount (SMT) light emitting diodes (LEDs) in the smallest industry-standard (0603) footprint available. With an ultra small form factor about the size of a pencil tip, these low-power LEDs use high-brightness chips to provide excellent illumination with minimum current consumption. These new ChipLED lamps from Avago are available in blue and phosphor white -- the colors most widel...

Power Sources Unlimited announces the XL160 Series of ultra small, highly efficient ac/dc power supplies which pack 160W of power into a 3” x 5” x 1.25” package. The XL160 Series features a universal 90-264VAC input with active PFC. Nine models provide single or multiple outputs (single output models have a secondary 12VDC/1A output). Two models provide ATX outputs in the same 3” x 5” package, perfect for applications where the end...

Now available from Link Microtek is a range of high-speed PIN diodes that are made from high-resistivity epitaxial silicon material, passivated with silicon dioxide to achieve high levels of stability and reliability.

Zetex Semiconductors has introduced a range of mid-voltage bipolar transistors in the SOT23 package, capable of handling a power dissipation of up to 1.25W. With the 3mm x 2.5mm footprint, these seven NPN and six PNP devices help to significantly increase circuit power density by replacing the much larger DPAK, SOT89 and SOT223 packaged parts.

NAD Electronics and Zetex Semiconductors announce the joint-development of high-performance digital amplifiers incorporating Zetex Class Z direct digital feedback amplifier (DDFATM) technology, a unique performance-optimised digital amplifier architecture.

Zetex Semiconductors has introduced a series of miniature NPN and PNP transistors for MOSFET gate driving in latest generation power supplies. The first bipolars to be provided in the SOT23FF package, with a footprint of 2.5mm x 3mm and an off-board height of just 1mm, the ZXTN and ZXTP transistors offer a lower saturation voltage and higher current gain hold up, leading to improved circuit efficiency and cooler running.

Providing an adjustable output current of 1A from a SOT23 package, the ZXLD1360 LED driver from Zetex Semiconductors offers higher power density than alternative and much larger SO8 devices. A buck regulator device, it operates over a supply range of 7V to 30V and is capable of handling up to 24W of output power in a wide range of high power LED illumination applications. Achieving up to 95% efficiency, this LED driver’s thermally enhanced con...

Zetex Semiconductors has added a pair of low voltage PNP transistors to its low saturation high current SOT23FF transistor range. With the footprint of the standard SOT23 package but with a reduced off board height of less than 1mm, the ZXTP25020CFF and ZXTP19020DFF will suit a range of slimline portable product designs.

An Enterprise Ireland client - Eblana Photonics - has won a significant European Space Agency (ESA) contract to develop lasers for use in the most precise atomic clocks that have ever been proposed. 'Atomic clocks' are the world's most accurate clocks and are used in the existing European Galileo satellite system design used for global positioning. These satellite-borne clocks must be highly accurate and stable since a deviation of even one nanos...

Photonic Products has launched a new range of 405nm wavelength stabilised laser diodes from ONDAX for applications which include Raman spectroscopy, flow cytometry and metrology / interferometry. The ONDAX 405nm blue-violet wavelength stabilised laser is a miniature laser in a standard TO 5.6mm package. The wavelength stabilisation is achieved by optical feedback using the ONDAX Volume Holographic Grating (VHG) PowerLocker which ensures a stable ...
