DTC143X series
NPN 100mA 50V Digital Transistors (Bias Resistor Built-in Transistors)
Datasheet
Parameter VCC
IC(MAX.) R1 R2
Value 50V 100mA 4.7kΩ 10kΩ
lFeatures 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) Only the on/off conditions need to be set for operation, making the circuit design easy.
