Overview
The DTA014TUBTL is a PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors within an SMD/SMT UMT3F (SOT-323FL-3) package. It operates with a maximum collector-emitter voltage of -50 V and a continuous collector current of -100 mA. The device includes a typical input resistance of 10 kOhms and maintains a DC current gain minimum of 68 at specified test conditions. Power dissipation is rated at 200 mW, supporting operation up to +150 C.
Feature Summary
- Integrates a PNP bipolar junction transistor with internal base and emitter-base resistors to simplify circuit design.
- Utilizes the compact UMT3F surface-mount package for efficient space utilization on printed circuit boards.
- Provides high-speed switching capabilities suitable for digital logic interface applications.
Applications
- General-purpose digital logic level shifting and signal buffering
- Switching circuits in consumer electronics and industrial control systems
- Interface modules requiring simplified bias resistor networks
Procurement Notes
Verify the specific suffix 'TUBTL' against official ROHM documentation to confirm the exact reel packaging configuration and tape-and-reel specifications. Ensure compatibility with standard surface-mount assembly processes. Confirm RoHS compliance status through the manufacturer's latest datasheet before final procurement decisions.
Selection Notes
Select this component when a PNP digital transistor with a 10 kOhm base resistor is required in a small UMT3F footprint. Compare performance metrics such as hFE and saturation voltage against alternative packages like SOT-323 or SC-85 if board space allows. Consider thermal dissipation limits relative to the application's ambient temperature constraints.
Part Context
This part belongs to the DTA014 series of pre-biased transistors from ROHM Semiconductor. The series offers various resistor combinations and polarity options within standardized surface-mount packages. The DTA014TUBTL specifically addresses designs needing PNP configuration with integrated biasing in a compact form factor.
Replacement Considerations
Consult ROHM's official substitution guide for equivalent parts with identical pinouts and electrical characteristics. Verify that any replacement maintains the same PNP polarity, voltage ratings, and package dimensions to ensure mechanical and functional compatibility without redesigning the PCB layout.
