dtd143ek npn 500ma 50v digital transistors (bias resistor built-in transistors) l outline l features 1) built-in biasing resistors, r 1 = r 2 = 4.7k w . 2) built-in bias resistors enable the configuration of l inner circuit an inverter circuit without connecting external input resistors (see inner circuit). 3) the bias resistors consist of thin-film resistors with complete isolation to allow negative biasing of the input. they also have the advantage of completely eliminating parasitic effects. 4) only the on/off conditions need to be set for operation, making the circuit design easy. 5) complementary pnp types :dtb143ek 6) lead free/rohs compliant. l application switching circuit, inverter circuit, interface circuit, driver circuit l packaging specifications reel size (mm) parameter value smt3 v cc 50v i c(max.) 500ma r 1 4.7k w r 2 4.7k w tape width (mm) basic ordering unit (pcs) marking dtd143ek smt3 2928 t146 180 8 3,000 f23 part no. package package size (mm) taping code dtd143ek sot - 346 (sc - 59) out in gnd 1/5 2012.07 - rev.d dat asheet www.rohm.com ? 2012 rohm co., ltd. all rights reserved.
