Overview
The DTA144EUAT106 is a PNP digital transistor with built-in resistors manufactured by ROHM Semiconductor. It operates with a collector-emitter voltage of -50V and a continuous collector current of -0.1A. The device features an input resistance (R1) of 47kΩ and an emitter-base resistance (R2) of 47kΩ, providing a DC current gain (hFE) range of 68 to unspecified upper limit under specified conditions. Power dissipation is rated at 0.2W. It is housed in a SOT-323 (UMT3/SC-70) surface-mount package with three terminals.
Feature Summary
- Integrates biasing resistors to simplify circuit design by eliminating external components.
- Supports AEC-Q101 automotive qualification standards for reliability.
- Enables easy configuration of inverter circuits through simplified on/off control.
Applications
- Automotive electronic systems requiring qualified discrete components.
- General-purpose switching applications utilizing single PNP configurations.
- Inverter circuits designed with minimal external component counts.
Procurement Notes
Verify the specific ordering suffix 'AFRA' or 'T106' against official ROHM documentation to ensure correct tape-and-reel packaging and compliance status. Confirm supply status as this variant may be designated not recommended for new designs depending on the exact suffix and production date. Cross-reference datasheet revision dates to validate parameter consistency before procurement.
Selection Notes
Select this component when a PNP digital transistor with 47kΩ input resistance is required in a compact SOT-323 package. Ensure the application voltage does not exceed -50V and current requirements remain within -0.1A limits. Verify thermal management capabilities for 0.2W power dissipation in the target enclosure environment.
Part Context
This part belongs to the DTA144 series of PNP digital transistors from ROHM. It shares pinout compatibility with other variants like DTA144EU3HZG but differs in packaging and specific electrical tolerances. The series is designed for space-constrained applications requiring integrated biasing solutions.
Replacement Considerations
DTA144EU3HZG offers identical pinout and package dimensions with similar electrical characteristics. Verify if the alternative meets AEC-Q101 requirements if automotive qualification is mandatory for the specific application context.
