DTA144EM / DTA144EE / DTA144EUA DTA144EKA / DTA144ESA Transistors Digital transistors (built-in resistors) DTA144EM / DTA144EE / DTA144EUA / DTA144EKA / DTA144ESA !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 device design easy. !Equivalent circuit OUT R1 IN R2 GND (+) OUT IN GND (+) !Structure PNP digital transistor (Built-in resistor type) !External dimensions (Units : mm) DTA144EM DTA144EE 1.2 0.8 1.0±0.1 (1) IN (2) GND (3) OUT ROHM : VMT3 (3) Abbreviated symbol : 16 (3) ROHM : SMT3 EIAJ : SC-59 0.4 +0.1 −0.05 All terminals have same dimensions +0.1 0.15 −0.06 Abbreviated symbol : 16 DTA144ESA 2±0.2 (15Min.) 5 ROHM : SPT EIAJ : SC-72 3Min. 3±0.2 4±0.2 0.45+0.15 −0.05 2.5 +0.4 −0.1 (1) (2) (3) 0.5 0.45 +0.15 −0.05 (1) GND (2) OUT (3) IN 0.3Min. 0.1Min.
