Bipolar Transistors

( 1 Oct 2006 )

A range of low voltage bipolar transistors from Zetex Semiconductors extends the power handling capability of the SOT23 package, enabling designers to shrink products by replacing SOT89 and SOT223 equivalent parts. Zetex is offering two NPN and two PNP devices, each capable of dissipating up to 1.25W. The ZXTN23015CFH and ZXTN25020DFH NPNs have VCE ratings of 15 and 20V respectively, while the ZXTP23015CFH and ZXTP25040DFH PNPs are in turn rated for 15 and 40V operation. Handling continuous currents up to 6 A, the transistor series enables increases in power density to be made, and by supporting pulse current peaks up to 15A, it provides the ability to drive higher capacitance MOSFETs and IGBTs at much higher speed in power supply applications.
