DDTC114YCA-7-F

Overview

The DDTC114YCA-7-F is an NPN pre-biased small signal surface mount transistor from Diodes Incorporated. It features built-in biasing resistors with nominal values of R1 = 10 kΩ and R2 = 47 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 (IC) of 100 mA, and a power dissipation (PD) of 200 mW. The DC current gain (hFE) has a minimum value of 68 at IC = 5 mA. The transition frequency (fT) is typically 250 MHz. Operating and storage temperature ranges extend from -55°C to +150°C.

Feature Summary

• Integrated biasing network with unequal resistor values for simplified circuit design
• Qualified to AEC-Q101 standards for high reliability applications
• Totally lead-free and fully RoHS compliant construction
• Halogen and antimony free "Green" device formulation

Applications

• Automotive electronic systems requiring AEC-Q101 qualified components
• General purpose switching and logic interface circuits
• Driver stages for low-power loads in consumer electronics

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm packaging quantity and compliance status. Confirm that the component meets all required environmental regulations for the intended deployment region. Ensure compatibility with standard surface mount assembly processes and reflow soldering profiles specified for the SOT-23 package type.

Selection Notes

Select this component when a single NPN transistor with integrated base and emitter resistors is required. Verify that the nominal resistance values of 10 kΩ and 47 kΩ align with the target circuit drive requirements. Consider the 50 V voltage rating and 100 mA current capacity relative to the load specifications. Evaluate thermal performance based on the 200 mW power dissipation limit in the final enclosure environment.

Part Context

This part belongs to the DDTC (R1≠R2 Series) CA family of pre-biased transistors manufactured by Diodes Incorporated. The series offers various combinations of internal resistor values within the same SOT-23 footprint. The 'CA' designation indicates specific resistor ratios distinct from other series variants. This configuration allows designers to replace discrete resistor-transistor networks with a single compact component.

Replacement Considerations

Direct replacements must match the NPN polarity, SOT-23 package, and similar electrical ratings. Verify that substitute parts offer comparable hFE and fT characteristics. Check if alternative manufacturers provide equivalent AEC-Q101 qualification if automotive reliability is required. Ensure pinout compatibility remains identical to avoid PCB layout modifications.
