DTC144E series Datasheet NPN 100mA 50V Digital Transistors (Bias Resistor Built-in Transistors) l Outline Parameter VCC Value IC(MAX.) 100mA R1 R2 47kΩ 47kΩ VMT3 EMT3F 50V l Features 1) Built-In Biasing Resistors, R1 = R2 = 47kΩ 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 PNP Types: DTA144E series 6) Complex transistors: EMH2/ UMH2N/ IMH2A/ EMH6/ UMH6N/ IMH6A （NPN type） 7) Lead Free/RoHS Compliant.
