datasheet www.rohm.com ? 201 4 rohm co., ltd. all rights reserved. imh21 npn 600ma 20v digital transistors (bias resistor built-in transistors) for muting. ? outline ? features 1) built-in biasing resistors 2) two dtc614t chips in one package. 3) low saturation voltage, typically v ce(sat) =40mv at i c / i b =50ma / 2.5ma, makes these transistors ideal for muting circuits. 4) these transistors can be used at high current levels, i c =600ma. ? inner circuit 5) built-in bias resistors enable the configuration of an inverter circuit without connecting external input resistors (see equivalent circuit). 6) 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. 7) lead free/rohs compliant. r 1 =10k ? ? application muting circuit ? packaging specifications parameter tr1 and tr2 smt6 v ceo 20v v ebo 12v i c 600ma r 1 10k ? tape width (mm) basic ordering unit (pcs) marking imh21 smt6 2928 t110 180 8 3,000 h21 part no. package package size (mm) taping code reel size (mm) imh21 sot-457 (sc-74) (4) (5) (6) (3) (2) (1) collector (4) (2) base (3) emitter (1) collector base (5) emitter (6) r 1 r 1 2014.10 - rev.c downloaded from: http:///
