Overview
The DTC144TU3HZGT106 is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SOT-323 (UMT3) surface-mount package. It integrates a bias resistor network configured as an R1 alone type with a typical input resistance of 47 kOhms. Key electrical parameters include a collector-emitter voltage (VCEO) of 50 V, a continuous collector current of 100 mA, and a power dissipation rating of 200 mW. The device features a minimum DC current gain (hFE) of 100 at 1 mA and 5 V, with a maximum operating frequency of 250 MHz. It supports a maximum operating temperature of +150°C and meets AEC-Q101 automotive grade standards.
Feature Summary
- Integrates a built-in bias resistor to simplify circuit design and reduce component count.
- Designed for high reliability and compliance with automotive quality standards.
- Optimized for compact surface-mount applications with low thermal mass.
Applications
- Inverter interface drivers
- Automotive electronic control units
- General-purpose switching circuits
Procurement Notes
Verify the specific suffix GT106 corresponds to the required tape-and-reel packaging quantity of 3000 units. Confirm that the SOT-323 package variant aligns with the target PCB footprint. Ensure the AEC-Q101 qualification status meets the specific automotive application requirements before finalizing procurement orders.
Selection Notes
Select this component when a single NPN switch with integrated base biasing is required in a small form factor. The 47 kOhm internal resistor value suits standard logic-level driving interfaces. Consider the 200 mW power dissipation limit for thermal management in dense layouts. Verify compatibility with the 50 V collector-emitter voltage rating against the system's maximum supply rails.
Part Context
This part belongs to the DTC144 series of bias resistor built-in transistors from ROHM. It shares the same functional core as DTC144TUAT106 but differs in packaging and automotive qualification. The 'TU3' designation indicates the SOT-323 package, while 'HZG' typically denotes automotive-grade specifications and specific reel configurations within the manufacturer's lineup.
Replacement Considerations
DTC144TUAT106 offers identical electrical characteristics but may differ in packaging or automotive certification status. DTA144TU3T106 is the PNP counterpart with matching pinout and similar performance metrics. Verify pin compatibility and thermal ratings when substituting with non-ROHM equivalents.
