Overview
The DDTA123TCA-7 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 2.2 kΩ. Key electrical specifications include a maximum collector-emitter voltage (VCEO) of -50 V, a continuous collector current (IC) of -100 mA, and a power dissipation (PD) of 200 mW at +25°C. The DC current transfer ratio (hFE) ranges from 100 to 600 at IC = -1mA and VCE = -5V. The unit operates within a temperature range of -55°C to +150°C.
Feature Summary
- Integrates a single built-in biasing resistor (R1 only) for simplified circuit design
- Utilizes epitaxial planar die construction for reliability
- Complies with RoHS directives and is halogen and antimony free
Applications
- General-purpose switching applications
- Driver circuits for low-power loads
- Logic level translation interfaces
Procurement Notes
Verify the specific ordering suffix against official documentation, as variations such as '-7-F' denote standard packaging configurations like reels. Confirm that the required component matches the exact R1 resistance value and polarity specified in the design requirements before procurement.
Selection Notes
Select this component when a PNP pre-biased transistor with a 2.2 kΩ base resistor is required in an SOT23 package. Ensure the application voltage does not exceed the -50 V collector-emitter rating and that the thermal management supports the 200 mW power dissipation limit under operating conditions.
Part Context
This part belongs to the DDTA1x3xCA family of PNP pre-biased transistors offered by Diodes Incorporated. The '123' designation specifically identifies the 2.2 kΩ internal resistor value. Complementary NPN types are available in the DDTC series.
Replacement Considerations
Direct substitutes within the same manufacturer's lineup include DDTA113TCA-7-F (1kΩ) or DDTA143TCA-7-F (4.7kΩ) if different resistance values are acceptable. Verify pinout compatibility and electrical ratings match the original design constraints.
