500mA / 50V Digital transistors (with built-in resistors) DTD143EK Dimensions (Unit : mm) 2.9 DTD143EK 1.1 0.4 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 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. 0.8 1.6 2.8 (3) (2) ( 1) 0.95 0.95 0.15 1.9 ROHM : SMT3 EIAJ : SC-59 Each lead has same dimensions 0.3Min.
