DTC014TUBTL

Overview

The DTC014TUBTL is a single NPN digital transistor manufactured by ROHM Semiconductor, integrating biasing resistors within a compact surface-mount package. It features a typical base resistor (R1) of 10 kOhms and an emitter-base resistor (R2) of 4.7 kOhms, yielding a resistance ratio of approximately 4.7. The device supports a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 50 mA. Key electrical parameters include a minimum DC current gain (hFE) of 35 at 5 mA and 10 V, a transition frequency of 250 MHz, and a power dissipation rating of 200 mW. It operates within a temperature range up to +150°C and utilizes the UMT3F (SOT-323FL) package.

Feature Summary

• Integrates built-in biasing resistors to simplify circuit design and reduce component count.
• Provides high-speed switching capabilities with a transition frequency of 250 MHz.
• Offers robust performance with a 50 V collector-emitter breakdown voltage and 50 mA continuous current capacity.
• Utilizes a compact UMT3F surface-mount package for efficient PCB space utilization.

Applications

• General-purpose switching circuits in consumer electronics.
• Driver stages for small-signal loads in portable devices.
• Logic level translation interfaces between microcontrollers and peripheral components.
• Biasing networks in amplifier input stages requiring integrated resistance.

Procurement Notes

Verify the specific suffix 'TUBTL' against official ROHM documentation to confirm the tape-and-reel packaging configuration and quantity per reel. Ensure compatibility with standard SMD reflow soldering profiles for the UMT3F package. Cross-reference the manufacturer part number with authorized distributors to confirm current production status and RoHS compliance details prior to ordering.

Selection Notes

Select this component when a single NPN digital transistor with a 10k/4.7k resistor ratio is required in a UMT3F package. Compare hFE minimums and VCEO ratings against alternative packages like SOT-323 or SC-85 if space constraints differ. Verify that the 200 mW power dissipation rating meets the thermal requirements of the target application environment.

Part Context

This part belongs to the ROHM DTC014 series of pre-biased NPN transistors. It shares functional similarities with variants such as DTC014EUBTL and DTC014YEBTL but differs in package type and specific internal resistor configurations. The series is designed for applications requiring simplified biasing without external discrete resistors.

Replacement Considerations

Direct substitutes may include DTC014EUBTL or DTC014YEBTL from ROHM, provided the package footprint and electrical parameters align with the design requirements. Verify pinout compatibility and ensure that the replacement part's power dissipation and voltage ratings meet or exceed the original specifications.
