The DTA144EKAT146 is a PNP pre-biased bipolar junction transistor manufactured by ROHM Semiconductor. It integrates a 47kΩ base resistor, simplifying circuit design by reducing external component count. The transistor is rated for a collector-emitter voltage of 50V and a continuous collector current of 30mA, with a power dissipation of 200mW.
This device offers a minimum DC current gain (hFE) of 68 at 5mA collector current and 5V collector-emitter voltage, ensuring reliable amplification in switching and signal processing applications. The maximum Vce saturation voltage is 300mV at 500µA base current and 10mA collector current, contributing to low power loss in saturated operation. With a transition frequency of 250MHz, it is suitable for moderate-speed switching circuits.
The DTA144EKAT146 is housed in a surface-mount SMT3 package (compatible with TO-236-3, SC-59, and SOT-23-3 footprints), making it ideal for compact PCB designs. The pre-biased configuration reduces board space and assembly cost, making it a practical choice for high-volume consumer and industrial electronics.
