dta143t series pnp -100ma -50v digital transistors (bias resistor built-in transistors) datasheet ll outline parameter value vmt3 emt3f v ceo -50v i c -100ma r 1 4.7k dta143tm dta143teb (sc-105aa) (sc-89) emt3 umt3f ll features 1) built-in biasing resistor 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 resistor s 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 types: dtc143t series 6) complex transistors: emb3/ umb3n/ imb3a/ ema3/ uma3n/ fma3a pnp type 7) lead free/rohs compliant. dta143te dta143tub sot-416(sc-75a) (sc-85) umt3 smt3 dta143tua dta143tka sot-323(sc-70) sot-346(sc-59) ll inner circuit b: base ll application c: collector switching circuit, inverter circuit, interface circ uit, e: emitter driver circuit ll packaging specifications part no. package package size taping code reel size (mm) tape width (mm) basic ordering unit.(pcs) marking dta143tm vmt3 1212 t2l 180 8 8000 93 dta143teb emt3f 1616 tl 180 8 3000 93 dta143te emt3 1616 tl 180 8 3000 93 dta143tub umt3f 2021 tl 180 8 3000 93 dta143tua umt3 2021 t106 180 8 3000 93 dta143tka smt3 2928 t146 180 8 3000 93 www.rohm.com ? 2013 rohm co., ltd. all rights reserved. 1/9 20130530 - rev.002 downloaded from: http:///
