DTC123TKA Datasheet NPN 100mA 50V Digital Transistors (Bias Resistor Built-in Transistors) llOutline Parameter Value SMT3 V 50V CEO I 100mA C R 2.2k 1 SOT-346(SC-59) llFeatures llInner circuit 1) Built-In Biasing Resistor 2) Built-in bias resistors enable the configuration of an inverter circuit without connecting external input resistors (see inner circuit) . 3) The bias resistors consist of thin-film resistors with complete isolation to allow negative biasing of the input. They also have the advantage of completely eliminating parasitic effects. 4) Only the on/off conditions need to be set for operation, making the circuit design easy. B: BASE 5) Lead Free/RoHS Compliant.
