dta144vka pnp -100ma -50v digital transistors (bias resistor built-in transistors) datasheet l l outline parameter value smt3 v cc -50 v i c(max.) -100 ma r 1 47 k r 2 10 k sot-346(sc-59) l l features l l inner circuit 1) built-in biasing resistors 2) built-in bias resistors enable the configuration of 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 npn type: dtc144vka 6) lead free/rohs compliant. l l application switching circuit, inverter circuit, interface circuit, driver circuit l l packaging specifications part no. package package size taping code reel size (mm) tape width (mm) basic ordering unit.(pcs) marking dta144vka smt3 2928 t146 180 8 3000 e56 www.rohm.com ? 2012 rohm co., ltd. all rights reserved. 1/5 20121023 - rev. 001
