Overview
The DDTC114TCA-7-F is an NPN pre-biased small signal transistor manufactured by Diodes Incorporated, housed in a surface-mount SOT23 package. It features a built-in base resistor (R1) with a nominal value of 10 kΩ and a tolerance of ±30%. The device supports a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current (IC) of 100 mA. Power dissipation is rated at 200 mW, with a thermal resistance (RθJA) of 625 °C/W. The DC current transfer ratio (hFE) ranges from 100 to 600 at IC = 1 mA, VCE = 5 V. The transition frequency (fT) is typically 250 MHz. Operating temperature spans -55°C to +150°C.
Feature Summary
- Epitaxial planar die construction for reliable performance
- Integrated single biasing resistor (R1 only) simplifies circuit design
- Totally lead-free and fully RoHS compliant
- Halogen and antimony free "Green" device
Applications
- General-purpose switching applications
- Driver circuits for logic interfaces
- High-frequency signal processing
Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation to ensure correct packaging and marking codes. Confirm that the component meets all applicable environmental directives, including RoHS 3 compliance, before finalizing procurement specifications. Cross-reference datasheet revision numbers to guarantee alignment with current manufacturing standards.
Selection Notes
Select this component when a single NPN pre-biased transistor with a 10 kΩ base resistor is required. Ensure the application voltage does not exceed the 50 V collector-emitter rating. Verify that the 200 mW power dissipation limit accommodates the thermal conditions of the target PCB layout. Consider the SOT23 package dimensions for footprint compatibility during the design phase.
Part Context
This part belongs to the DDTC (R1-ONLY SERIES) CA family from Diodes Incorporated. It is designed as a surface-mount alternative to discrete resistor-transistor networks. The series includes complementary PNP types (DDTA) and variants with different resistor values. The 'CA' designation indicates the specific pinout and internal configuration used in the SOT23 housing.
Replacement Considerations
Direct substitutes within the same series include DDTC113TCA-7-F (1 kΩ), DDTC124TCA-7-F (22 kΩ), and DDTC144TCA-7-F (47 kΩ). For automotive applications requiring AEC-Q101 qualification, consider the DDTC143TCAQ variant. Ensure any replacement maintains the same SOT23 package and electrical ratings.
