imh23 transistors 1/2 dual digital transistors imh23 z features in addition to the features of regular digital transistors. 1) low saturation voltage, typically v ce (sat) =40mv at i c / i b =50ma / 2.5ma, makes these transistors ideal for muting circuits. 2) these transistors can be used at high current levels, i c =600ma. 3) two dtc643t chips in a smt package. z structure npn digital transistor (built-in resistor type) z external dimensions (unit : mm) each lead has same dimensions abbreviated symbol : h23 smt6 ( 6 ) ( 5 ) ( 4 ) 0.3min. 0.15 0.3 1.1 0.8 ( 3 ) 2.8 1.6 1.9 2.9 0.95 ( 2 ) 0.95 ( 1 ) 1pin mark z equivalent circuit r 1 (4) (5) (6) (3) (2) (1) r 1 r 1 =4.7k? z absolute maximum ratings (ta=25 c) parameter symbol v cbo v ceo 300(total) p c tstg limits 20 20 ?55 to +150 unit v v mw ? ? 200mw per element must not be a exceeded. c c collector-base voltage collector-emitter voltage collector power dissipation storage temperature emitter-base voltage collector current v ebo i c 12 600 v ma tj 150 junction temperature
