DTD122JK Transistors 500mA / 50V Digital transistors (with built-in resistors) DTD122JK zExternal dimensions (Unit : mm) zApplications Inverter, Interface, Driver SMT3 2.9 1.1 0.4 zFeatures 1) Built-in bias resistors enable the configuration of an inverter circuit without connecting external input resistors. 2) The bias resistors consist of thin-film resistors with complete isolation to allow negative biasing of the input, and parasitic effects are almost completely eliminated. 3) Only the on / off conditions need to be set for operation, making the device design easy. 4) Higher mounting densities can be achieved. 0.8 1.6 2.8 (3) (2) 0.15 (1)Emitter 1.9 0.3Min.
