Overview
The DDTC114EUAQ-7-F is an NPN pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features built-in biasing resistors with a nominal value of 10 kOhms each (R1 = R2). The device is housed in a SOT-323 package and supports a maximum supply voltage of 50 V and a continuous collector current of 100 mA. Power dissipation is rated at 200 mW, with an operating temperature range from -55°C to +150°C. It has a minimum DC current gain of 30 and a transition frequency of 250 MHz.
Feature Summary
- Epitaxial planar die construction for reliable performance
- Built-in biasing resistors simplify circuit design
- Qualified to AEC-Q101 standards for automotive applications
- Totally lead-free and fully RoHS compliant
Applications
- Automotive electronic systems requiring high reliability
- General-purpose switching applications
- Driver circuits for logic interfaces
Procurement Notes
Verify the specific ordering suffix 'Q' indicates automotive qualification status as defined by the manufacturer. Confirm packaging details such as reel size and tape width match production requirements. Ensure compliance with environmental directives like RoHS 3 and REACH is documented for regulatory adherence.
Selection Notes
Select this component when an NPN digital transistor with 10 kOhm internal biasing resistors is required. Consider the SOT-323 package dimensions for space-constrained PCB layouts. Verify that the 50 V supply voltage and 100 mA current ratings meet the application's electrical demands.
Part Context
This part belongs to the DDTC (R1 = R2 Series) UA family of NPN pre-biased transistors. It shares electrical characteristics with standard versions but includes automotive-specific qualification markings. Complementary PNP types are available within the same series for push-pull configurations.
Replacement Considerations
Standard non-automotive equivalents like DDTC114EUA-7-F may be considered if automotive qualification is not required. Verify pinout compatibility and thermal resistance values before substitution.
