The DTC143XKAT146 is an NPN pre-biased bipolar junction transistor from ROHM Semiconductor, designed for surface-mount applications. It features a built-in 10 kΩ base resistor, simplifying circuit design by reducing component count. Key electrical characteristics include a collector current rating of 100 mA, collector-emitter breakdown voltage of 50 V, and a transition frequency of 250 MHz. The device offers a DC current gain (hFE) of 30 minimum at 10 mA, 5 V, and a saturation voltage of 300 mV maximum at 10 mA collector current with 500 µA base current. Power dissipation is rated at 200 mW. The transistor is housed in a compact SOT-23 package (also known as TO-236-3, SC-59, SMT3) suitable for automated assembly. This pre-biased transistor is ideal for switching and amplification circuits in consumer electronics, industrial controls, and other low-power applications where space and simplicity are priorities.
