Overview
The DDTC144TE-7-F is an NPN pre-biased transistor from Diodes Incorporated, housed in a SOT523 surface-mount package. It features a built-in biasing resistor (R1) with a nominal value of 47 kΩ. The device supports a collector-emitter voltage (VCEO) of 50 V and a continuous collector current (IC) of 100 mA. Power dissipation is rated at 150 mW, with a thermal resistance (RθJA) of 833 °C/W. The DC current transfer ratio (hFE) ranges from 100 to 600 at IC = 1mA and VCE = 5V. The gain-bandwidth product (fT) is typically 250 MHz. Operating and storage temperatures span from -55°C to +150°C.
Feature Summary
- Epitaxial planar die construction for reliable performance
- Built-in single biasing resistor simplifies circuit design
- AEC-Q101 qualified for automotive applications requiring specific change control
- Totally lead-free and fully RoHS compliant
Applications
- Automotive electronics requiring AEC-Q101 qualification
- General-purpose switching applications
- Driver circuits for low-power loads
Procurement Notes
Verify the component status as Active through official Diodes Incorporated channels or authorized distributors. Confirm compliance with RoHS 3 and REACH regulations. Check for PPAP capability if used in automotive supply chains. Ensure packaging details match the required reel size and quantity per reel specifications.
Selection Notes
Select this part when a compact NPN solution with integrated base resistance is needed. The 47 kΩ internal resistor sets the input impedance. Consider the SOT523 package dimensions for PCB layout constraints. Verify that the 100 mA current rating and 50 V voltage limits meet the application requirements.
Part Context
This component belongs to the DDTC (R1-ONLY SERIES) E family, which includes various resistor values. It is specifically designed for surface-mount assembly. The 'TE' suffix indicates the SOT523 package type. The '-7-F' suffix denotes the standard tape and reel packaging format.
Replacement Considerations
Direct substitutes within the same series include DDTC114TE-7-F (10kΩ), DDTC124TE-7-F (22kΩ), and DDTC115TE-7-F (100kΩ). Cross-manufacturer equivalents may exist but require verification of pinout and electrical characteristics.
