Overview
The DDTC113TCA-7-F is an NPN pre-biased transistor from Diodes Incorporated, housed in a surface-mount SOT23 package. It integrates a single internal biasing resistor (R1) with a nominal value of 1 kΩ. The device supports a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current (IC) of 100 mA. Electrical characteristics include a minimum DC current transfer ratio (hFE) of 100 at IC = 1 mA and VCE = 5 V. Thermal performance allows for a power dissipation (PD) of 200 mW and operation within a temperature range of -55°C to +150°C.
Feature Summary
- Integrates a single built-in biasing resistor (R1 only) to simplify circuit design.
- Utilizes epitaxial planar die construction for reliable semiconductor performance.
- Manufactured using halogen-free and antimony-free green molding compounds.
Applications
- General-purpose switching applications requiring simplified base drive circuits.
- Driver stages for low-power loads where external biasing components are restricted.
- Automotive electronics utilizing AEC-Q101 qualified variants within the series.
Procurement Notes
Verify that the specific orderable part number matches the required R1 resistance value, as the DDTC113TCA designation specifically corresponds to a 1 kΩ input resistor. Confirm compliance requirements such as RoHS 3 and REACH status directly against the manufacturer's latest documentation before finalizing procurement specifications.
Selection Notes
Select this component when a fixed 1 kΩ base resistor is appropriate for the target logic interface. Compare the 100 mA collector current limit and 50 V breakdown voltage against the application's peak load requirements. Ensure the SOT23 thermal resistance and power dissipation limits accommodate the expected duty cycle and ambient operating conditions.
Part Context
This component belongs to the DDTC (R1-ONLY SERIES) CA family produced by Diodes Incorporated. The series provides various NPN pre-biased transistors differentiated primarily by their integrated base resistor values, ranging from 1 kΩ to 200 kΩ across different model suffixes.
Replacement Considerations
Direct substitutes within the same manufacturer family include DDTC123TCA-7-F (2.2 kΩ), DDTC143TCA-7-F (4.7 kΩ), and DDTC114TCA-7-F (10 kΩ). Cross-manufacturer replacements must match the SOT23 footprint, 50 V rating, and 100 mA current capacity while verifying equivalent hFE and saturation voltage parameters.
