DTC143XUAT106 Description

Short technical summary and product information.

The DTC143XUAT106 is an NPN pre-biased bipolar junction transistor manufactured by ROHM Semiconductor.

 

It integrates a 10 kΩ base resistor, reducing external component count and simplifying circuit design. Electrical characteristics include a maximum collector-emitter voltage of 50 V, a maximum collector current of 100 mA, and a power dissipation of 200 mW. The transistor offers a minimum DC current gain (hFE) of 30 at Vce=5 V and Ic=10 mA, with a typical transition frequency of 250 MHz.

 

Housed in a surface-mount SC-70 (SOT-323) package, also designated as UMT3, it is suitable for high-density PCB layouts. The part is RoHS3 compliant and has an MSL rating of 1 (unlimited).
