DTA144W series Datasheet PNP -100mA -50V Digital Transistors (Bias Resistor Built-in Transistors) l Outline Parameter VCC Value IC(MAX.) -100mA R1 R2 47k 22k EMT3 UMT3 -50V DTA144WE DTA144WUA SOT-416(SC-75A) SOT-323(SC-70) SMT3 l Features 1) Built-In Biasing Resistors 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. 5) Complementary NPN Types: DTC144W series 6) Lead Free/RoHS Compliant.
