500mA / 50V Digital transistors (with built-in resistors) DTD114EK Dimensions (Unit : mm) 2.9 DTD114EK 1.1 0.4 Structure NPN epitaxial planar silicon transistor (Resistor built-in type) 0.8 (3) 1.6 2.8 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.
