| dta144e series pnp -100ma -50v digital transistors (bias resistor built-in transistors) datasheet ll outline parameter value vmt3 emt3f v cc -50v i c(max.) -100ma r 1 47k dta144em dta144eeb r 2 47k (sc-105aa) (sc-89) emt3 umt3f ll features 1) built-in biasing resistors, r 1 = r 2 = 47k 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: dtc144e series 6) complex transistors: emb2/ umb5n/ imb2a/ ema2/ uma2n/ fma2a pnp type 7) lead free/rohs compliant. dta144ee dta144eub sot-416(sc-75a) (sc-85) umt3 smt3 dta144eua dta144eka sot-323(sc-70) sot-346(sc-59) ll inner circuit ll application switching circuit, inverter circuit, interface circ uit, driver circuit ll packaging specifications part no. package package size taping code reel size (mm) tape width (mm) basic ordering unit.(pcs) marking dta144em vmt3 1212 t2l 180 8 8000 16 dta144eeb emt3f 1616 tl 180 8 3000 16 dta144ee emt3 1616 tl 180 8 3000 16 dta144eub umt3f 2021 tl 180 8 3000 16 dta144eua umt3 2021 t106 180 8 3000 16 dta144eka smt3 2928 t146 180 8 3000 16 www.rohm.com ? 2012 rohm co., ltd. all rights reserved. 1/10 20121023 - rev.001 downloaded from: http:///
