DTB114EK Datasheet PNP -500mA -50V Digital Transistors (Bias Resistor Built-in Transistors) Outline Parameter Value VCC 50V 500mA 10k 10k IC(MAX.) R1 R2 SMT3 OUT IN GND DTB114EK SOT‐346 (SC‐59) Inner circuit Features 1) Built-In Biasing Resistors, R1 = R2 = 10k. OUT R1 2) Built-in bias resistors enable the configuration of an inverter circuit without connecting external input resistors (see equivalent 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 Available.(DTD114EK) 6) Lead Free/RoHS Compliant.
