Overview
The DTA114TUBTL is a PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in bias 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 input resistor (R1) of 10 kOhms and an emitter-base resistor (R2) of 10 kOhms. Packaged in the SOT-323FL (UMT3F) surface-mount format, it offers a power dissipation of 200 mW and a DC current gain (hFE) ranging from 100 to 600 at specified test conditions. The component supports a maximum operating temperature of +150°C.
Feature Summary
- Integrates dual bias resistors (R1 and R2) within a single compact package to eliminate external components for inverter circuits.
- Provides high DC current gain suitable for switching applications requiring reliable on/off control.
- Designed for surface-mount technology with a small footprint to support dense PCB layouts.
Applications
- Inverter circuits for logic level translation
- Interface drivers between microcontrollers and peripheral devices
- General-purpose switching applications in consumer electronics
Procurement Notes
Verify the specific ordering suffix TL against the manufacturer's latest datasheet to confirm tape-and-reel packaging details. Ensure compatibility with RoHS directives if required by your manufacturing standards. Cross-reference the part number with authorized distributors to confirm current availability status and lead times, as supply chain conditions may vary.
Selection Notes
Select this component when a PNP digital transistor with equal bias resistors (10kΩ/10kΩ) is required in a SOT-323FL package. Compare the 200 mW power dissipation rating against thermal constraints. Consider the complementary NPN type DTC114TUB for paired designs. Verify that the -50 V breakdown voltage meets the system's maximum voltage requirements.
Part Context
This part belongs to the DTA114 series of pre-biased transistors from ROHM Semiconductor. The series integrates bipolar junction transistors with internal resistors to reduce board space and assembly costs. The TUB variant specifically denotes the SOT-323FL package configuration, distinguishing it from other form factors like SOT-23 or SOT-416 within the same electrical family.
Replacement Considerations
DTA114EU3HZG is listed as a similar specification replacement with comparable electrical characteristics but utilizes a standard SOT-323 package instead of SOT-323FL. Verify pinout compatibility and physical dimensions before substitution.
