DTC144EM / DTC144EE / DTC144EUA DTC144EKA / DTC144ESA Transistors 100mA / 50V Digital transistors (with built-in resistors) DTC144EM / DTC144EE / DTC144EUA / DTC144EKA / DTC144ESA zApplications Inverter, Interface, Driver zFeatures 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 negative 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. zStructure NPN epitaxial planar silicon transistor (Resistor built-in type) zExternal dimensions (Unit : mm) DTC144EM DTC144EE 0.7 1.6 0.55 0.3 0.2 (3) (2) 0.2 (1)(2) 0.22 0.4 0.4 0.13 (1) IN (2) GND (3) OUT 0.8 ROHM : VMT3 0.2 2.9 DTC144EKA 1.6 2.8 2.1 0.1Min. 0.15 1.3 (1) GND (2) IN (3) OUT Each lead has same dimensions Abbreviated symbol : 26 4.0 (2) (1) 0.95 0.95 ROHM : SMT3 EIAJ : SC-59 0.15 1.9 0.3Min. 1.25 (1) (2) 0.65 0.65 (1) GND (2) IN (3) OUT Each lead has same dimensions Abbreviated symbol : 26 2.0 (15Min.) 3Min. 3.0 DTC144ESA 0.8 (3) (3) ROHM : UMT3 EIAJ : SC-70 1.1 0.4 0.7 0.2 0.3 (1) GND (2) IN (3) OUT 1.0 ROHM : EMT3 Abbreviated symbol : 26 0.9 2.0 0.15 0.5 0.5 Abbreviated symbol : 26 DTC144EUA (1) 0.2 0.5 0.1Min. 0.8 1.2 0.8 (3) 1.6 1.2 0.32 0.45 2.5 0.5 0.45 5.0 ROHM : SPT EIAJ : SC-72 (1) (2) (3) (1) GND (2) OUT (3) IN Abbreviated symbol : C144ES Rev.A 1/3 DTC144EM / DTC144EE / DTC144EUA DTC144EKA / DTC144ESA Transistors zPackaging specifications Part No. zEquivalent circuit Package VMT3 EMT3 UMT3 SMT3 SPT Packaging type Taping Taping Taping Taping Taping Code T2L TL T106 T146 TP Basic ordering unit (pieces) 8000 3000 3000 3000 5000 - - - - - - - - - OUT R1 IN R2 GND DTC144EM DTC144EE - DTC144EUA - - DTC144EKA - - - DTC144ESA - - - OUT IN - GND - R1=R2=47k zAbsolute maximum ratings (Ta=25C) Parameter Symbol Limits DTC144EM DTC144EE DTC144EUA DTC144EKA DTC144ESA Unit Supply voltage VCC 50 V Input voltage VIN -10 to +40 V IO 30 IC(Max.) 100 Output current mA Power dissipation PD Junction temperature Tj 150 C Storage temperature Tstg -55 to +150 C 150 200 300 mW zElectrical characteristics (Ta=25C) Parameter Input voltage Output voltage Input current Output current Symbol Min.
