The DTC143EUBTL is a single NPN digital transistor manufactured by ROHM Semiconductor, featuring built-in biasing resistors to simplify circuit design. It operates with a collector-emitter voltage of 50 V and a continuous collector current of 100 mA. The device includes an internal base resistor (R1) and emitter-base resistor (R2), both typically valued at 4.7 kOhms, resulting in a resistance ratio of 1. Key electrical specifications include a minimum DC current gain (hFE) of 30 at 10 mA and 5 V, a transition frequency of 250 MHz, and a maximum power dissipation of 200 mW. It is housed in a UMT3F (SOT-323FL) surface-mount package.
Verify the specific ordering suffix against the manufacturer's datasheet to confirm pinout and electrical tolerances. Ensure the component meets RoHS3 compliance requirements for your assembly process. Confirm that the UMT3F package dimensions align with your PCB footprint constraints before finalizing procurement.
Select this component when a compact NPN solution with integrated biasing is required for low-power switching applications. Consider the 50 V breakdown voltage and 100 mA current limit to ensure adequate headroom for the target load. Verify that the 200 mW power dissipation rating is sufficient for the expected operating temperature range.
This part belongs to the DTC143 series of digital transistors from ROHM Semiconductor. It is designed as a drop-in replacement for discrete resistor-transistor networks, reducing board space and assembly complexity. The UMT3F package offers a small form factor suitable for dense consumer electronics layouts.
DTC143EU3T106 is listed as a similar specification alternative with a UMT3 package. DTC143EUBHZG is noted as not recommended for new designs.
