| DTB143TK Transistors -500mA / -40V Digital transistors (with built-in resistor) DTB143TK Applications Inverter, Interface, Driver External dimensions (Unit : mm) 2.9 1.1 Features 1) Built-in bias resistors enable the configuration of an inverter circuit without connecting external input resistors (see equivalent circuit). 2) The bias resistors consist of thin-film resistors with complete isolation to allow positive biasing of the input. They also have the advantage of almost completely eliminating parasitic effects. 3) Only the on / off conditions need to be set for operation, making the device design easy. 0.4 (3) 0.8 (2) (1) 1.6 2.8 0.95 0.95 0.15 1.9 Each lead has same dimension ROHM : SMT3 EIAJ : SC-59 Abbreviated symbol : F93 (1) Emitter (2) Base (3) Collector Structure PNP epitaxial planar silicon transistor (Resistor built-in type) Equivalent circuit C Packaging specifications Package Packaging type Code Basic ordering unit (pieces) SMT3 Taping T146 3000 B R1 E B : Base C : Collector E : Emitter Part No. DTB143TK R1=4.7k Absolute maximum ratings (Ta=25C) Parameter Symbol VCBO VCEO VEBO IC PC Tj Tstg Limits -50 -40 -5 -500 200 150 -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 Rev.B 0.3Min. 1/2 DTB143TK Transistors Electrical characteristics (Ta=25C) Parameter Collector-base breakdown voltage Collector-emitter breakdown voltage Emitter-base breakdown voltage Collector cutoff current Emitter cutoff current Collector-emitter saturation voltage DC current transfer ratio Input resistance Transition frequency Characteristics of built-in transistor Symbol BVCBO BVCEO BVEBO ICBO IEBO VCE(sat) hFE R1 fT Min. -50 -40 -5 - - - 100 3.29 - Typ.
