ROHM DTC143EU3T106 NPN Digital Transistor, 100 mA, 50 V, 3-Pin SOT-323

TC143EU3 is an digital transistor (Resistor built-in type transistor). Built-in bias resistors enable the configuration of an inverter circuit without connecting external input resistors.

Built-In Biasing Resistors, R1 = R2 = 4.7kΩ
Built-in bias resistors enable the configuration of an inverter circuit without connecting external input resistors (see inner circuit) .
Only the on/off conditions need to be set for operation, making the circuit design easy.
Complementary PNP Types: DTA143E series
