DTC144EKAT146 Description

Short technical summary and product information.

The DTC144EKAT146 is an NPN pre-biased transistor manufactured by ROHM Semiconductor. It integrates a bias resistor (R1 = 47 kΩ) to simplify circuit design by reducing external component count. The transistor is rated for a maximum collector-emitter voltage of 50 V and a maximum collector current of 100 mA, with a power dissipation of 200 mW. It offers a DC current gain (hFE) of at least 68 at 5 mA, 5 V, and a transition frequency of 250 MHz. The collector-emitter saturation voltage is 300 mV maximum at Ib=500 µA, Ic=10 mA. The device is housed in a compact SMT3 package (TO-236-3, SC-59, SOT-23-3) suitable for surface-mount assembly. This pre-biased transistor is commonly used in switching and amplifier applications where space and component count are critical. The built-in resistor helps ensure consistent biasing and reduces board area. The part is RoHS3 compliant and has an MSL of 1 (unlimited).
