Overview
The DTA144GU3HZGT106 is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SOT-323-3 surface-mount package. It integrates bias resistors to simplify circuit design. Key electrical parameters include a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. The device features a typical input resistance of 47 kOhms and a minimum DC current gain (hFE) of 68 at 5 mA and 5 V. It supports a maximum operating frequency of 250 MHz with a power dissipation rating of 200 mW. The component operates up to +150°C and meets AEC-Q101 automotive standards.
Feature Summary
- Integrates bias resistors for simplified digital circuit interfacing
- Automotive-grade reliability compliant with AEC-Q101 standards
- Compact SOT-323-3 surface-mount packaging for space-constrained designs
Applications
- Inverter control circuits
- Interface driver stages
- General-purpose digital switching applications
Procurement Notes
Verify the complete part number including suffixes against official ROHM documentation to ensure correct configuration. Confirm AEC-Q101 qualification status if automotive compliance is required. Check datasheet revisions for any updates to mechanical dimensions or electrical limits before finalizing procurement specifications.
Selection Notes
Select this component for NPN switching applications requiring integrated base biasing. Ensure the 50 V VCEO rating exceeds the maximum circuit voltage. Verify that the 100 mA collector current capability matches load requirements. Consider the 47 kOhm input resistance value for drive current calculations and logic level compatibility.
Part Context
This part belongs to the ROHM DTC144/DTA144 series of bias resistor built-in transistors. It shares the SOT-323 form factor with other variants in the lineup but differs in polarity and internal resistor configurations. The 'GU' designation typically indicates specific internal resistor values and NPN polarity within the product family.
Replacement Considerations
The DTA144EU3HZGT106 is listed as a similar level replacement with the same pinout and package. Verify polarity differences (PNP vs NPN) and resistor values before substitution. Cross-reference with ROHM's official replacement guide for confirmed equivalents.
