Overview
The DTA015TUBTL is a single PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in biasing resistors within an SOT-323FL (EMT3F) surface-mount package. It operates with a collector-emitter voltage of -50 V and a continuous collector current of -100 mA. The device includes a base resistor (R1) of 10 kOhms and an emitter-base resistor (R2) of 47 kOhms. Key electrical characteristics include a minimum DC current gain (hFE) of 68 at -5 mA and -10 V, a maximum operating frequency of 250 MHz, and a power dissipation rating of 200 mW. The component supports a maximum junction temperature of +150°C.
Feature Summary
- Integrates internal biasing resistors to simplify circuit design by eliminating external components.
- Provides high-speed switching capabilities suitable for digital logic applications.
- Offers compact surface-mount packaging for space-constrained designs.
Applications
- General-purpose inverter circuits
- Driver circuits for relays and solenoids
- Logic level shifting interfaces
Procurement Notes
Verify the specific suffix 'TUBTL' against official ROHM documentation to confirm the exact reel quantity and tape specifications. Ensure compatibility with standard SMT reflow profiles and check for RoHS compliance status in the latest datasheet before finalizing procurement orders.
Selection Notes
Select this component when a PNP digital transistor with a 10 kOhm base resistor is required. Compare the 10 kOhm input resistance against other series variants like DTA015EUB (100 kOhm) or DTA014YUB (1 kOhm) to match the specific drive current requirements of the application circuit.
Part Context
This part belongs to the DTA015 series of digital transistors from ROHM. It serves as the PNP counterpart to NPN types such as the DTC015 series. The device is designed to replace discrete resistor-transistor combinations, reducing board space and assembly costs while maintaining consistent electrical performance across production batches.
Replacement Considerations
Direct functional substitutes within the same family include DTA015EUBTL and DTA015EEBTL, provided the difference in base resistance values (10k vs 100k) is acceptable for the circuit design. Verify pinout compatibility for the EMT3F/SOT-323FL package.
