The DTC143XU3T106 is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in a surface-mount SOT-323 (UMT3) package. It integrates biasing resistors to simplify circuit design without external components. Key electrical parameters include a collector-emitter voltage of 50 V and a continuous collector current of 100 mA. The device features a typical input resistance of 4.7 kOhms with an emitter-base resistance ratio of 2.1. It operates up to a maximum frequency of 250 MHz and dissipates 200 mW of power. The minimum DC current gain is 30 at 10 mA and 5 V, with a collector-emitter saturation voltage of 300 mV.
Verify the specific suffix against official documentation, as variations such as HZGT may indicate automotive qualification or distinct packaging formats. Confirm RoHS compliance status through the manufacturer's datasheet rather than distributor summaries. Ensure the ordering code matches the required resistor values and package type for the target application.
Select this component when a compact NPN solution with integrated biasing is required for low-power switching. The 4.7 kOhm input resistance suits standard logic interfaces. Consider the 50 V rating for general-purpose signal processing. Verify thermal constraints given the 200 mW dissipation limit in the small SOT-323 footprint.
This part belongs to the DTC143 series of pre-biased transistors from ROHM. It shares the SOT-323 form factor with other variants like DTC143EU3 and DTC143ZU3 but differs in internal resistor configurations. The series is designed to replace discrete resistor-transistor combinations, reducing board space and assembly complexity in consumer and industrial electronics.
Direct substitutes within the same family include DTC143EU3HZGT106 and DTC143ZU3HZGT106, which share the SOT-323 package but feature different internal resistor ratios. Cross-manufacturer equivalents require matching the 50 V rating, 100 mA current capacity, and specific R1/R2 values.
