New Generation Of Highly Efficient Low VCEsat Transistors

Apr 28, 2010 9:45 AM

NXP Semiconductors announced the launch of the first eight products from its new 4th generation low VCEsat (BISS) transistors. The product family comes in two optimized branches - an ultra-low VCEsat and a high-speed switching branch. They are available in a voltage range from 20 V to 60 V and are housed in small SMD packages SOT23 (2.9 x 1.3 x 1 mm) and SOT457 (2.9 x 1.5 x 1 mm).

Setting a new benchmark for reduced on-state-resistance and keeping switching times to an absolute minimum, these transistors live up to their name as Breakthrough In Small-Signal (BISS) transistors. Transistors from the ultra-low VCEsat branch enable ultra-low saturation voltage below 50 mV at 1 A. The four new high-speed switching transistors come with reduced switching and storage times down to 125 ns. The new BISS-4 products demonstrate that bipolar transistor technology is an ideal option for switching applications that require higher performance and reduced switching losses.

The new BISS-4 transistors provide high circuit efficiency, low power losses and generate less heat than standard transistors in the same package. With a DC collector current of 4.3 A (peak ICM 8 A) in a small SOT23 package, these new products double the performance of former low VCEsat transistors in SOT23. The new BISS-4 types are designed for loadswitch, switch mode power supply (SMPS) and power management functions in high-volume consumer, communication, computing and automotive applications.

All eight new transistors are AEC-Q101 qualified and come in packages that are free of halogens and antimony oxides and comply with non-flammability classification UL 94V-0 and RoHS standards. Further types in SMD packages SOT89, SOT223 and SO-8 will expand the new low VCEsat (BISS) transistor portfolio end of Q1 2010. NXP launched the first BISS transistors family ten years ago and is a leading supplier for these products.

NXP's new low VCEsat transistors are ready for ordering. Samples are available immediately for design-in. Volume pricing ranges from $0.06 to $0.08 (USD).
