Product Overview
The DTC143ZE is an NPN digital transistor with an integrated bias resistor network, designed to simplify inverter, switching, and interface circuits without requiring external input resistors. It supports a 50V supply voltage, 100mA output current, and a typical input resistance of 4.7kΩ with an R2/R1 resistance ratio of 10. Its built-in bias network helps reduce component count, simplify circuit design, and save PCB space.
Packaged in a compact SOT-523 surface-mount package, the DTC143ZE is suitable for logic-controlled switching, digital interfaces, microcontroller output stages, and other low-current control applications.
