DTC124G series NPN 100mA 50V Digital Transistors (Bias Resistor Built-in Transistors) Datasheet llOutline Parameter Value UMT3 SMT3 V 50V CEO I 100mA C R 22k DTC124GUA DTC124GKA SOT-323(SC-70) 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) Complementary PNP Types: DTA124G series 5) Lead Free/RoHS Compliant.
