Zetex provides a comprehensive range of high brightness LED drivers to suit a

Analog signal processing and solution supplier Zetex of the power management put out brand-new adoption encapsulated bipolar transistor series SOT23 a few days ago. They can realize that capsulate the same current treatment function with greater SOT223 with smaller size, reduce the size of the p-c board effectively. The area of SOT23 device is only 2.5 millimetres

Zetex makes the best of its advanced lead wire chassis designing and bipolar process ability, develops two new NPN device and two PNP devices together, every section of power consumption is 1.25W. The specified VCE voltage of ZXTN23015CFH and ZXTN25020DFH NPN is 15V and 20V respectively; The ZXTP23015CFH and ZXTP25040DFH PNP one is 15V and 40V respectively. Zetex Asian executive vice president Lin BoWen points out, the new transistor-resistor logic series can be dealt with high to the continuous current of 6A, promote the power density of the products greatly. They can support high to the pulse crest current of 15A, can drive the electric capacity more high MOSFET and IGBT at the higher speed in the power is employed. Another characteristic of these SOT23 bipolar transistors, have extremely low saturation voltage - -Calculate with 15V NPN device, it is only 30mV under 1A collector current. So, they can be used for producing the high-efficiency switch, are especially suitable for with the battery-driven apparatus, can dissipate, keep in absolute minimum level heat. In addition, because of their gain great, large-scale supported and can be driven by the integrated circuit, do not need extra buffer circuit.

Analog signal processing and supplier Zetex semi-conductive company of the power management scheme announced a few days ago, expand with the distribution partner rich prosperous electron (Future Electronics) Cooperation discuss association. In the past, were only responsible for Zetex richly and prosperously in the distribution business of the area of Europe and North America. The cooperation range of both sides will be expanded to the whole world, and will contain Zetex a full range of power and SIGPROC signal processing products in the future. Zetex chief executive Bob Conway shows: "It is rich commercial networks prosperous for electron which doesn't have complete and consummate technology resource, good at offering the appropriate local products to customer to support, this has already been affirmed; And Zetex and rich and prosperous common goal, become and lead the global heavy-duty benefit simulation solution leader. Making use of and concluding the global cooperative agreement richly and prosperously, we can finish this long-range goal. " The international business executive vice president Dan Casey of rich prosperous electron points out: "We and Zetex have very sane cooperation relations, both sides go forward hand in hand, supplement and complement each other. We have the same ideas even more in offering the intact solution, are devoted to optimizing the product design in various fields, including products capsulation, function and electric consumption,etc.. We expect to extend the cooperation relation in the Asian-Pacific area with Zetex, found greater achievement. "
