DTC144GE / DTA144GUA / DTC144GKA / DTC144GSA Transistors Digital transistors (built-in resistor) DTC144GE / DTC144GUA / DTC144GKA / DTC144GSA zFeatures 1) The built-in bias resistors consist of thin-film resistors with complete isolation to allow negative biasing of the input, and parasitic effects are almost completely eliminated. 2) Only the on / off conditions need to be set for operation, making device design easy. 3) Higher mounting densities can be achieved. zCircuit schematic C B R E E : Emitter C : Collector B : Base zAbsolute maximum ratings (Ta=25°C) Parameter Collector-base voltage Collector-emitter voltage Emitter-base voltage Symbol Limits Unit VCBO VCEO 50 V V V mA VEBO IC Collector current DTC144GE Collector Power DTC144GUA / DTC144GKA dissipation DTC144GSA Junction temperature Storage temperature 50 5 100 150 Pc 200 mW 300 Tj 150 Tstg −55 to +150 C C zPackage, marking, and packaging specifications Part No. DTC144GE DTC144GUA DTC144GKA DTC144GSA Package Marking EMT3 K26 UMT3 K26 SMT3 K26 SPT − Packaging code Basic ordering unit (pieces) TL 3000 T106 3000 T146 3000 TP 5000 Rev.A 1/2 DTC144GE / DTA144GUA / DTC144GKA / DTC144GSA Transistors zElectrical characteristics (Ta=25°C) Symbol Min.
