Overview
The DDTC114GCA-7-F is an NPN pre-biased small signal surface mount transistor from Diodes Incorporated, housed in a SOT-23 package. It features an epitaxial planar die construction and includes a built-in biasing resistor (R2 only) with a nominal value of 10 kΩ. Key electrical ratings include a collector-emitter voltage (VCEO) of 50 V, a continuous collector current (IC) of 100 mA, and power dissipation (PD) of 200 mW at 25°C. The device operates within a temperature range of -55°C to +150°C, offers a minimum DC current gain (hFE) of 30, and has a typical gain-bandwidth product of 250 MHz.
Feature Summary
- Integrates a single internal biasing resistor (R2) to simplify circuit design
- Utilizes epitaxial planar die construction for reliable performance
- Compliant with RoHS standards and free of lead, halogen, and antimony
Applications
- General-purpose switching applications
- Driver circuits for logic interfaces
- Low-power digital signal processing
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging details. Confirm that the component meets required environmental compliance standards such as RoHS and Halogen-free specifications before procurement. Ensure compatibility with standard SMD/SMT assembly processes.
Selection Notes
Select this component when a compact NPN solution with integrated base resistance is required. Consider the 10 kΩ R2 value for appropriate base drive requirements. Verify thermal management capabilities given the 200 mW power dissipation limit in the SOT-23 package.
Part Context
This part belongs to the DDTC1xxGCA series of pre-biased transistors manufactured by Diodes Incorporated. The 'GCA' suffix indicates the SOT-23 package type and specific marking code. It is part of a family offering various resistor values for different biasing needs.
Replacement Considerations
Check datasheets for alternative pre-biased transistors with matching VCEO, IC, and R2 values. Verify pinout compatibility and package dimensions for direct replacement.
