DTA144GUAT106 Description

Short technical summary and product information.

The DTA144GUAT106 is a PNP pre-biased digital transistor (also known as a bias resistor built-in transistor) manufactured by ROHM Semiconductor. It integrates a 47kΩ bias resistor (R1) directly into the transistor, enabling the construction of inverter circuits without external input resistors. This simplifies PCB design and reduces component count.

 

Key electrical specifications include a collector-emitter voltage (VCEO) of -50V, a collector current (IC) of -100mA, and a power dissipation of 200mW. The DC current gain (hFE) is a minimum of 68 at Vce=-5V and Ic=-5mA. The transistor offers a transition frequency of 250 MHz, making it suitable for switching and driver applications.

 

The device is housed in a UMT3 package (SC-70 / SOT-323), which is a small surface-mount package ideal for space-constrained designs. It is supplied on tape and reel with 3000 pieces per reel. The part is RoHS compliant and has an MSL rating of 1 (unlimited).
