The DTC143Z series NPN 100mA 50V digital transistors (bias resistor built-in transistors) have built-in bias resistors that allow the configuration of an inverter circuit without connecting external input resistors (see inner circuit). 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. Operation only requires the on/off conditions to be set, making the circuit design easy.
The DTC143ZEB is a digital NPN transistor featuring a built‑in 4.7 kΩ bias resistor, allowing inverter circuits without external resistors. It offers a maximum collector current of 100 mA, a supply voltage rating of 50 V, and is RoHS‑compliant.
The datasheet lists absolute maximum ratings, typical electrical parameters such as input resistance, DC current gain, and transition frequency, as well as detailed package dimensions for the EMT3F 1616 TL (SC‑89) form factor.
