Overview
The DDTA124TCA-7-F is a PNP pre-biased transistor from the DDTA (R1-only series) CA manufactured by Diodes Incorporated. It features an epitaxial planar die construction in a surface-mount SOT23 package. The device integrates a single internal biasing resistor with a nominal value of 22 kΩ. Key electrical ratings include a collector-emitter voltage of -50 V, a continuous collector current of -100 mA, and a power dissipation capacity of 200 mW. The component operates within a temperature range of -55°C to +150°C and exhibits a DC current transfer ratio (hFE) ranging from 100 to 600.
Feature Summary
- Integrates a single built-in biasing resistor for simplified circuit design
- Utilizes epitaxial planar die construction for reliable performance
- Complies with RoHS standards and is halogen and antimony free
Applications
- General-purpose switching applications
- Driver circuits requiring integrated base biasing
- Automotive electronics systems
Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation to confirm packaging details and availability status. Confirm that the component meets all required environmental compliance standards for the intended deployment environment before finalizing procurement decisions.
Selection Notes
Select this component when a PNP configuration with a 22 kΩ base resistor is required. Ensure the application voltage does not exceed the -50 V collector-emitter rating and that thermal management accommodates the 200 mW power dissipation limit within the specified operating temperature range.
Part Context
This part belongs to the DDTA R1-only series, which distinguishes itself by integrating only a base resistor rather than dual resistors found in other digital transistor families. It serves as the PNP counterpart to the DDTC NPN series, providing complementary options for designers needing pre-biased solutions in compact SOT23 packages.
Replacement Considerations
Direct replacements within the same family include DDTA114TCA-7-F and DDTA144TCA-7-F, which share identical package and electrical characteristics but feature different nominal base resistance values.
