Overview
The DDTC114EUA-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 kΩ for both R1 and R2. The device operates within a supply voltage range up to 50 V and supports 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 utilizes an SOT-323 package and meets AEC-Q101 standards for high reliability.
Feature Summary
- Epitaxial planar die construction
- Built-in biasing resistors with equal values (R1 = R2)
- Qualified to AEC-Q101 automotive standards
- Totally lead-free and fully RoHS compliant
Applications
- Automotive electronic circuits requiring high reliability
- General-purpose switching applications
- Driver circuits for logic interfaces
Procurement Notes
Verify the specific ordering suffix '-7-F' against official documentation to confirm packaging details, including reel size and tape width. Confirm compliance markings such as 'N13' match the intended production requirements. Ensure that the component meets all relevant environmental directives before finalizing procurement specifications.
Selection Notes
Select this component when an NPN digital transistor with 10 kΩ internal biasing resistors is required. Consider the SOT-323 package dimensions for space-constrained designs. Verify that the 100 mA collector current and 50 V voltage ratings align with the circuit's maximum operational limits and thermal management capabilities.
Part Context
This part belongs to the DDTC (R1 = R2 Series) UA family of NPN pre-biased transistors. Complementary PNP types are available in the DDTA series. The product line includes various resistor values ranging from 2.2 kΩ to 100 kΩ, offering flexibility for different input impedance requirements in digital switching applications.
Replacement Considerations
Publicly confirmed substitute part numbers include DDTC114EUAQ-7-F for automotive-grade variants. Other potential replacements may exist within the same manufacturer's portfolio or from alternative suppliers, but direct substitution requires verification of electrical parameters and pin compatibility.
