Overview
The DDTA125TCA-7-F is a PNP pre-biased transistor from the DDTA (R1-ONLY SERIES) CA family, manufactured by Diodes Incorporated. It features an epitaxial planar die construction and integrates a single internal biasing resistor with a nominal value of 200 kΩ. The device operates within a collector-emitter voltage range of -50 V and supports a continuous collector current of -100 mA. Electrical characteristics include a DC current transfer ratio (hFE) ranging from 100 to 600 at -1 mA and -5 V, and a gain-bandwidth product of 250 MHz. Thermal performance specifies a maximum power dissipation of 200 mW and a junction-to-ambient thermal resistance of 625 °C/W. The component is housed in a surface-mount SOT23 package.
Feature Summary
- Integrates a single built-in biasing resistor (R1 only) to simplify circuit design.
- Utilizes epitaxial planar die construction for reliable semiconductor performance.
- Complies with RoHS 3 standards and is halogen and antimony free.
Applications
- General-purpose switching applications requiring integrated base biasing.
- Driver circuits for low-power loads where external base resistors are undesirable.
- Digital logic interface circuits utilizing PNP transistor configurations.
Procurement Notes
Verify the obsolete status of this specific part number before initiating any procurement activities. Confirm availability through authorized distributors or secondary market channels, as standard factory production may no longer be active. Ensure that any sourced units match the original specifications and packaging requirements for your application.
Selection Notes
Select this component when a PNP pre-biased transistor with a 200 kΩ base resistor is required. Compare against the DDTA124TCA-7-F for 22 kΩ or DDTA115TCA-7-F for 100 kΩ if different biasing values are needed. Ensure the SOT23 package footprint and -50 V rating align with the target circuit constraints.
Part Context
This component belongs to the DDTA R1-Only Series CA, which consists of PNP pre-biased transistors in SOT23 packages. The series offers various resistor values to accommodate different drive requirements while maintaining a consistent form factor and electrical profile across the family.
Replacement Considerations
The datasheet lists DDTA125TCA-7-F as Obsolete. No direct substitute part numbers are provided in the official documentation. Engineers should evaluate alternative PNP pre-biased transistors with similar 200 kΩ base resistance and SOT23 packaging from the same or other manufacturers.
FAQ
What is the nominal value of the internal biasing resistor?
The nominal value of the internal biasing resistor (R1) is 200 kΩ.
What is the maximum collector-emitter voltage?
The maximum collector-emitter voltage (VCEO) is -50 V.
Is this device suitable for automotive applications?
For automotive applications requiring AEC-Q100 qualification and IATF 16949 manufacturing, customers must contact Diodes Incorporated directly, as standard parts may not meet these specific criteria.
