DTA143ESA
DTA143EM / DTA143EE / DTA143EUA DTA143EKA / DTA143ESA Transistors Digital transistors (built-in resistors) DTA143EM / DTA143EE / DTA143EUA / DTA143EKA / DTA143ESA !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 (with built-in resistors) !External dimensions (Units : mm) DTA143EM DTA143EE 1.2 0.8 1.6±0.2 1.0±0.1 0.2 0.5 0.5 +0.1 0.2−0.05 0.8 (2) (3) 0.4 0.4 1.2 0.32 0.2 0.7±0.1 +0.1 0.2−0.05 0.55±0.1 (1) IN (2) GND (3) OUT ROHM : VMT3 (3) +0.1 0.3 −0.05 ROHM : EMT3 Abbreviated symbol : 13 DTA143EKA 0.8±0.1 0.95 0.95 (2) (2) 0~0.1 Abbreviated symbol : 13 (3) (1) GND (2) IN (3) OUT ROHM : SMT3 EIAJ : SC-59 +0.1 0.15 −0.06 0.4 +0.1 −0.05 All terminals have same dimensions Abbreviated symbol : 13 4±0.2 2±0.2 (15Min.) 5 ROHM : SPT EIAJ : SC-72 3Min. 3±0.2 DTA143ESA 0.45+0.15 −0.05 2.5 +0.4 −0.1 (1) (2) (3) 0.5 0~0.1 +0.15 0.45 −0.05 (1) GND (2) OUT (3) IN 0.3Min. 0.3+0.1 0.15±0.05 −0 All terminals have same dimensions 2.8±0.2 2.1±0.1 (1) 1.6+0.2 −0.1 (3) ROHM : UMT3 EIAJ : SC-70 (1) GND (2) IN (3) OUT 1.1+0.2 −0.1 1.9±0.2 0.7±0.1 0.2 1.25±0.1 (1) 2.9±0.2 0.9±0.1 1.3±0.1 0.65 0.65 0.15±0.05 Abbreviated symbol : 13 2.0±0.2 0.1Min.
