-500mA / -50V Digital transistors (with built-in resistors) DTB123EK Applications Inverter, Interface, Driver Dimensions (Unit : mm) DTB123EK 2.9 1.1 0.4 0.8 (3) 1.6 2.8 (2) (1) 0.95 0.95 0.15 1.9 ROHM : SMT3 EIAJ : SC-59 0.3Min. 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 the device design easy.
