Overview
The DDTC144ECAQ-7-F is an NPN pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features built-in biasing resistors where R1 equals R2, with a nominal resistance of 47 kOhms each. The device operates with a maximum supply voltage (VCC) of 50 V and a continuous collector current (IC) of 100 mA. Electrical characteristics include a minimum DC current gain (hFE) of 80 at VO = 5V and IO = 5mA, and a transition frequency (fT) of 250 MHz. Power dissipation is rated at 200 mW, with an operating temperature range from -55°C to +150°C. It is housed in an SOT-23 package.
Feature Summary
- Epitaxial planar die construction for high reliability
- Built-in biasing resistors with equal values (R1 = R2)
- Qualified to AEC-Q101 standards for automotive applications
- Totally lead-free and fully RoHS compliant
Applications
- Automotive electronic circuits requiring AEC-Q101 qualification
- General-purpose switching applications
- Driver circuits for low-power loads
Procurement Notes
Verify the component status as Active on official manufacturer channels before procurement. Confirm compliance with AEC-Q101 automotive standards and PPAP capability requirements if applicable to your specific manufacturing process. Ensure the ordering suffix matches the required reel size and quantity specifications provided in the official documentation.
Selection Notes
Select this component when an NPN digital transistor with equal base and emitter biasing resistors is required. The 47 kOhm resistor value suits applications needing moderate input drive currents. Consider the 200 mW power dissipation limit and SOT-23 package constraints for thermal management in dense PCB layouts.
Part Context
This part belongs to the DDTC (R1 = R2 SERIES) CA family from Diodes Incorporated. It is specifically designated for automotive use due to its AEC-Q101 qualification. Complementary PNP types are available in the DDTA series. The 'Q' suffix indicates automotive grade qualification, while '-7-F' denotes the standard 3,000-unit reel packaging format.
Replacement Considerations
Direct substitutes within the same family include DDTC144ECA-7-F for non-automotive applications. For equivalent electrical performance without automotive qualification, verify compatibility with other DDTC144 variants. Always confirm pinout and resistor values match exactly when substituting.
