DTC143ZUAT106 Description

Short technical summary and product information.

The DTC143ZUAT106 is an NPN pre-biased digital transistor from ROHM Semiconductor, part of the DTC143Z series. It integrates bias resistors R1 (4.7kΩ) and R2 (47kΩ) directly into the transistor package, enabling the configuration of an inverter circuit without external input resistors. This simplifies circuit design and reduces component count.

 

Key electrical specifications include a maximum supply voltage (VCC) of 50V, a maximum collector current (IC) of 100mA, and a power dissipation of 200mW. The device offers a DC current gain (hFE) of 80 minimum at 10mA and 5V, and a transition frequency (fT) of 250 MHz typical. The built-in resistor ratio (R2/R1) is nominally 10.

 

The DTC143ZUAT106 is housed in a surface-mount UMT3 package (SOT-323), making it suitable for compact designs. It is supplied in tape and reel packaging with a standard quantity of 3000 pieces per reel. Typical applications include inverter circuits, interface circuits, and driver circuits.
