dtc123tka transistors rev.a 1/2 200ma / 50v digital transistor (with built-in resistor) dtc123tka z applications inverter, interface, driver z features 1) built-in bias resistors enable the configuration of an inverter circuit without connecting external input resistors. 2) the bias resistors consist of thin-film resistors with complete isolation to allow negative biasing of the input, and parasitic effects are almost completely eliminated. 3) only the on/ off conditions need to be set for operation, making the device design easy. 4) higher mounting densit ies can be achieved. z structure npn epitaxial planar silicon transistor z packaging specifications part no. dtc123tka smt3 taping t146 3000 package packaging type code basic ordering unit (pieces) z external dimensions (unit : mm) each lead has same dimensions abbriviated symbol : 02 smt3 (1)emitter (2)base (3)collector ( 2 ) ( 1 ) 2.8 1.6 0.4 ( 3 ) 2.9 1.9 0.95 0.95 0.8 0.15 0.3min. 1.1 z equivalent circuit c b r 1 =2.2k ? e r 1 e : emitter c : collector b : base z absolute maximum ratings (ta=25 c) parameter symbol limits 50 50 5 100 200 150 ?55 to +150 unit v v v ma mw c c collector-base voltage collector-emitter voltage emitter-base voltage collector current collector power dissipation junction temperature storage temperature v cbo v ceo v ebo i c pc tj tstg
