Overview
The DDTC123YCA-7-F is an NPN pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features built-in biasing resistors with nominal values of R1 = 2.2 kΩ and R2 = 10 kΩ. The device utilizes epitaxial planar die construction in a SOT-23 package. Key electrical parameters include a maximum supply voltage (VCC) of 50 V, a continuous collector current (IO) of 100 mA, and a power dissipation (PD) of 200 mW. The DC current gain (hFE) has a minimum value of 33. Operating and storage temperature ranges extend from -55°C to +150°C.
Feature Summary
- Built-in biasing resistors enable inverter circuit configuration without external input resistors
- Totally lead-free and fully RoHS compliant
- Halogen and antimony free "Green" device
- Qualified to AEC-Q101 standards for high reliability
Applications
- Inverter circuits
- Driver circuits
- Switching applications
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging details such as reel size and quantity per reel. Confirm compliance requirements including RoHS and halogen-free status. Ensure the component meets AEC-Q101 qualification if automotive grade reliability is required. Cross-reference marking codes and date code keys for traceability purposes.
Selection Notes
Select this component when an NPN pre-biased transistor with a 2.2 kΩ base resistor and 10 kΩ emitter-base resistor is required. Consider the 50 V supply voltage limit and 100 mA output current capability. Evaluate thermal resistance and power dissipation constraints relative to ambient temperature conditions. Verify package compatibility with the SOT-23 footprint.
Part Context
This part belongs to the DDTC (R1≠R2 SERIES) CA family of NPN pre-biased transistors. It is distinct from other series members by its specific resistor ratio of 2.2 kΩ to 10 kΩ. The product line includes complementary PNP types designated as DDTA. The device is designed for surface mount applications requiring integrated biasing solutions.
Replacement Considerations
Complementary PNP types are available within the same product family. Other variants in the DDTC series offer different resistor ratios but share similar electrical characteristics. Verify pinout and package dimensions when substituting with equivalent components from other manufacturers.
