DTC144WUAT106 Description

Short technical summary and product information.

The DTC144WUAT106 is an NPN epitaxial planar silicon transistor with built-in bias resistors from ROHM Semiconductor. It integrates R1=47kΩ and R2=22kΩ resistors, enabling inverter, interface, and driver circuit configurations without external input resistors. The device is rated for a maximum collector-emitter voltage of 50V and a continuous collector current of 30mA, with a power dissipation of 200mW. It offers a minimum DC current gain (hFE) of 56 at 5mA, 5V and a transition frequency of 250MHz. The transistor is housed in a surface-mount UMT3 package (SC-70, SOT-323), suitable for compact PCB designs. The built-in thin-film resistors provide complete isolation, allowing negative input biasing and minimizing parasitic effects. This part is ideal for space-constrained applications requiring simple on/off control.
