DDTC114WCA-7-F

Overview

The DDTC114WCA-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 = 10 kOhms and R2 = 4.7 kOhms. The device operates within a supply voltage range up to 50 V and supports a continuous collector current of 100 mA. Electrical characteristics include a minimum DC current gain (hFE) of 24 at 10 mA, a transition frequency of 250 MHz, and a maximum power dissipation of 200 mW. It is housed in an SOT-23 package and complies with AEC-Q101 standards.

Feature Summary

• Integrated dual biasing resistors (R1 ≠ R2) for simplified circuit design
• Qualified to AEC-Q101 automotive reliability standards
• Totally lead-free and fully RoHS compliant construction
• Halogen and antimony-free green device packaging

Applications

• Automotive electronic systems requiring high reliability components
• General-purpose switching applications in consumer electronics
• Driver circuits for low-power loads and logic level translation

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm that the ordering suffix matches the required reel size and tape width specifications. Ensure compliance with RoHS and REACH directives as stated in the datasheet. Check for PPAP capability requirements if used in automotive manufacturing processes. Validate date code markings against production records.

Selection Notes

Select this part when a single NPN transistor with specific internal resistor ratios is needed. The 10k/4.7k ratio suits applications requiring moderate base drive currents. Consider thermal resistance limits during high-duty cycle operations. Compare against complementary PNP types if push-pull configurations are required.

Part Context

This component belongs to the DDTC114 series of pre-biased transistors from Diodes Incorporated. It shares the same electrical and thermal performance as other variants in the CA family but differs in internal resistor values. The -7-F suffix indicates standard packaging with AEC-Q101 qualification.

Replacement Considerations

Direct substitutes must match the SOT-23 package, NPN polarity, and 10k/4.7k resistor ratio. Verify that alternative parts meet the same AEC-Q101 qualification and RoHS compliance standards. Check for equivalent hFE and saturation voltage specifications.
