DTC144EM / DTC144EE / DTC144EUA DTC144EKA / DTC144ESA Transistors Digital transistors (built-in resistors) DTC144EM / DTC144EE / DTC144EUA / DTC144EKA / DTC144ESA 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 device design easy. zEquivalent circuit OUT R1 IN R2 GND OUT IN GND zStructure NPN digital transistor (Built-in resistors) zExternal dimensions (Unit : mm) DTC144EM DTC144EE 1.2 0.8 1.0±0.1 (1) IN (2) GND (3) OUT ROHM : VMT3 (3) 0 to 0.1 0.3 +0.1 0.15±0.05 −0 All terminals have same dimensions (1) GND (2) IN (3) OUT Abbreviated symbol : 26 2.8±0.2 1.6+0.2 −0.1 2.1±0.1 (2) 0 to 0.1 (3) ROHM : SMT3 EIAJ : SC-59 +0.1 0.15 −0.06 0.4 +0.1 −0.05 All terminals have same dimensions 0.3Min.
