Overview
The DDTC114EUA-7 is a single NPN pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features built-in biasing resistors with nominal values of R1 = 10 kΩ and R2 = 10 kΩ, resulting in a resistance ratio of 1. The device operates with a maximum supply voltage (VCC) of 50 V and a continuous collector current (IC) of 100 mA. Power dissipation is rated at 200 mW, with an operating temperature range from -55°C to +150°C. The gain-bandwidth product (fT) is typically 250 MHz. It utilizes SOT323 packaging.
Feature Summary
- Epitaxial planar die construction for high reliability
- Integrated 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 AEC-Q101 qualification
- General-purpose switching applications
- Driver circuits for low-power loads
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm compliance status and packaging details. Standard products differ from automotive variants only where specified. Confirm moisture sensitivity level and tape width requirements before procurement to ensure compatibility with assembly equipment.
Selection Notes
Select this component when a single NPN pre-biased transistor with 10 kΩ internal resistors is required. Ensure the 50 V supply voltage and 100 mA current ratings meet circuit demands. Consider the SOT323 package dimensions for board layout constraints. Verify thermal resistance requirements relative to ambient temperature conditions.
Part Context
This part belongs to the DDTC (R1 = R2 Series) UA family of NPN pre-biased transistors. Complementary PNP types are available within the DDTA series. The device shares electrical characteristics with other members of the series, differentiated primarily by resistor values and output current ratings.
Replacement Considerations
Complementary PNP types such as DDTA114EUA are available. Other manufacturers offer similar pre-biased transistors, but verify pinout compatibility and electrical parameters before substitution.
