Overview
The DDTC115ECA-7-F is an NPN pre-biased small signal surface mount transistor from Diodes Incorporated, housed in a SOT23 package. It features built-in biasing resistors where R1 equals R2, with a nominal resistance of 100 kΩ. The device supports a maximum supply voltage (VCC) of 50 V and a continuous collector current of 100 mA. Power dissipation is rated at 200 mW, with an operating temperature range spanning -55°C to +150°C. It includes an input resistor tolerance of ±30% and a gain-bandwidth product of 250 MHz.
Feature Summary
- Epitaxial planar die construction with complementary PNP types available
- Built-in biasing resistors configured as R1 = R2
- Qualified to AEC-Q101 standards for high reliability applications
- Totally lead-free and fully RoHS compliant
Applications
- Automotive electronic circuits requiring AEC-Q101 qualification
- General-purpose switching applications utilizing integrated biasing
- Surface mount designs constrained by SOT23 footprint requirements
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm compliance status and packaging details. The standard reel size is 7 inches with a tape width of 8 mm and a quantity of 3,000 units per reel. Confirm that the component meets the required environmental standards for the intended deployment environment before finalizing procurement orders.
Selection Notes
Select this component when a single NPN transistor with equal internal biasing resistors is required. Ensure the design accommodates the 100 kΩ nominal resistance value and the 100 mA maximum collector current limit. Verify that the SOT23 package dimensions align with the PCB layout constraints and thermal management requirements of the target application.
Part Context
This part belongs to the DDTC (R1 = R2 Series) CA family of pre-biased transistors manufactured by Diodes Incorporated. The series provides integrated biasing solutions to simplify circuit design. The 'CA' designation indicates the specific resistor configuration and package type used within this product line.
Replacement Considerations
Direct substitutes include other NPN pre-biased transistors with matching 100 kΩ biasing resistors and SOT23 packaging. Verify electrical parameters such as VCEO, IC, and PD to ensure compatibility. Check for equivalent AEC-Q101 qualification if automotive reliability is required.
