Overview
The DTC144GU3HZGT106 is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SOT-323 (UMT3) surface-mount package. It features a built-in bias resistor configuration with R2 alone type topology and a typical input resistance of 47 kOhms. Key electrical parameters include a collector-emitter voltage (VCEO) of 50 V, continuous collector current of 100 mA, and power dissipation of 200 mW. The device supports a maximum operating frequency of 250 MHz and operates within a temperature range of -55°C to +150°C. It meets AEC-Q101 automotive standards.
Feature Summary
- Integrates bias resistors to simplify circuit design without external components
- Utilizes thin-film resistors for complete isolation and negative bias capability
- Eliminates parasitic oscillation effects through internal resistor structure
- Complies with AEC-Q101 automotive grade reliability standards
Applications
- Inverter circuits
- Interface drivers
- Automotive electronic systems
Procurement Notes
Verify the specific suffix GT106 corresponds to the tape and reel packaging format with 3000 units per reel. Confirm RoHS compliance status through official manufacturer documentation. Ensure the component matches the UMT3/SOT-323 footprint requirements for your PCB layout. Cross-reference the datasheet revision date to confirm parameter accuracy against your design specifications.
Selection Notes
Select this component when a single NPN digital transistor with 47 kOhm base resistance is required. The 50 V rating suits low-voltage switching applications. Consider the complementary PNP model DTA144GU3HZG if a matched pair is needed. Verify that the 200 mW power dissipation limit accommodates your thermal design constraints in the SOT-323 package.
Part Context
This part belongs to the DTC144 series of bias resistor built-in transistors from ROHM. The GU3 designation indicates the specific resistor ratio and package type. The GT106 suffix denotes the taping packaging configuration. This series is designed for high-reliability applications requiring simplified biasing networks in compact form factors.
Replacement Considerations
The DTC144EU3HZGT106 is listed as a similar level replacement with the same pinout and package. Verify that the electrical characteristics, particularly the hFE gain and voltage ratings, meet your application requirements before substitution.
