Overview
The DTA144TU3T106 is a PNP digital transistor manufactured by ROHM Semiconductor, featuring a built-in bias resistor (R1) of 47 kOhms. It operates with a collector-emitter voltage (VCEO) of -50 V and a continuous collector current of -100 mA. The device has a minimum DC current gain (hFE) of 100 at -1 mA and -5 V, with a maximum operating frequency of 250 MHz. Power dissipation is rated at 200 mW, and the maximum operating temperature reaches +150°C. It is housed in an SOT-323-3 package for surface mount applications.
Feature Summary
- Integrates a single 47 kOhm bias resistor to simplify circuit design by eliminating external input resistors.
- Enables straightforward inverter circuit configuration through simple on/off condition settings.
- Provides high-speed switching capability suitable for interface and driver applications.
Applications
- Inverter circuits
- Interface circuits
- Driver circuits
Procurement Notes
Verify the specific suffix T106 corresponds to the tape and reel packaging format containing 3000 units per reel. Confirm RoHS compliance status directly from the manufacturer's datasheet before procurement. Ensure the ordering part number matches the exact electrical specifications required for the target application design.
Selection Notes
Select this component when a PNP digital transistor with a 47 kOhm base resistor is required. The SOT-323-3 package is suitable for space-constrained surface mount designs. Verify that the -50 V collector-emitter voltage rating meets the system's power supply requirements.
Part Context
This part belongs to the DTA144T series of PNP digital transistors from ROHM Semiconductor. The series includes variants with different resistance values and packages, such as the DTA144TM in SOT-723. The TU3 designation specifically indicates the SOT-323 package type within this product family.
Replacement Considerations
Check for direct substitutes within the DTA144T series or other manufacturers' PNP digital transistors with identical 47 kOhm resistance and SOT-323 packaging. Ensure pinout compatibility and equivalent electrical ratings are maintained during substitution.
