100mA / 50V Digital transistors (with built-in resistors) DTC123EM / DTC123EE / DTC123EUA / DTC123EKA zApplications Inverter, Interface, Driver zFeatures 1) Built-in bias resistors enable the configuration of an inverter circuit without connecting external input resistors (see the 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) zDimensions (Unit : mm) DTC123EM 2.0 DTC123EUA 0.9 0.2 (3) 0.8 1.2 1.25 (3) (1)(2) 0.13 0.65 0.65 0.5 (1) IN (2) GND (3) OUT 0.8 ROHM : VMT3 ROHM : UMT3 EIAJ : SC-70 Abbreviated symbol : 22 DTC123EKA 0.4 0.55 1.6 2.8 1.6 0.1Min. 0.2 0.15 (2) 0.95 0.95 (1) GND (2) IN (3) OUT 1.0 ROHM : EMT3 (1) 0.3Min. 0.8 (1) 0.5 0.5 0.15 ROHM : SMT3 EIAJ : SC-59 1.9 (1) GND (2) IN (3) OUT Abbreviated symbol : 22 Abbreviated symbol : 22 zPackaging specifications Type 0.8 (3) (3) (2) (1) GND (2) IN (3) OUT 1.1 2.9 0.7 0.3 0.15 1.3 Abbreviated symbol : 22 DTC123EE 1.6 0.1Min. 0.4 0.4 0.2 (1) (2) 0.2 0.22 2.1 1.2 0.32 0.7 0.2 0.3 zEquivalent circuit Package VMT3 EMT3 UMT3 SMT3 Packaging type Taping Taping Taping Taping Code T2L TL T106 T146 Basic ordering unit (pieces) 8000 3000 3000 3000 − − − − − OUT R1 IN R2 GND DTC123EM DTC123EE − DTC123EUA − − DTC123EKA − − OUT IN − GND − R1=R2=2.2kΩ www.rohm.com c 2009 ROHM Co., Ltd.
