Overview
The DDTC114TCA-7-F is an NPN pre-biased transistor in a SOT23 package. It features a built-in biasing resistor (R1) with a nominal value of 10 kΩ and a tolerance of ±30%. The device has a collector-emitter voltage (VCEO) of 50 V, a collector current (IC) of 100 mA, and a power dissipation (PD) of 200 mW. The DC current transfer ratio (hFE) ranges from 100 to 600 at IC = 1 mA, VCE = 5 V. The gain-bandwidth product (fT) is typically 250 MHz. Operating temperature range is -55°C to +150°C.
Feature Summary
- Epitaxial planar die construction for reliable performance
- Built-in single biasing resistor (R1 only) simplifies circuit design
- Totally lead-free and fully RoHS compliant
- Halogen and antimony free "Green" device
Applications
Procurement Notes
Verify the exact part number suffix against official Diodes Incorporated documentation to confirm packaging details and active status. Ensure compliance with specific environmental directives such as RoHS 3 and REACH requirements relevant to your region. Confirm that the SOT23 package dimensions match your PCB footprint specifications before finalizing procurement.
Selection Notes
Select this component when a compact NPN switching solution with integrated base resistance is required. The 10 kΩ internal resistor reduces external component count. Verify that the 200 mW power dissipation rating and 50 V voltage limits suit the target application's electrical constraints. Consider the SOT23 package size for space-constrained designs.
Part Context
This component belongs to the DDTC (R1-ONLY SERIES) CA family from Diodes Incorporated. It is specifically designed as an NPN pre-biased transistor. The 'CA' suffix indicates the SOT23 package type. Other variants in this series offer different resistor values and packages.
Replacement Considerations
Check datasheets for alternative NPN pre-biased transistors in SOT23 packages. Ensure equivalent VCEO, IC, PD, and R1 values. Verify pinout compatibility and thermal characteristics. Consult manufacturer substitution guides for confirmed equivalents.
