Overview
The DDTA123TCA-7-F is a PNP pre-biased transistor from Diodes Incorporated, housed in an SOT-23 package. It features built-in biasing resistors with R1 only, having a nominal value of 2.2 kΩ and a tolerance of ±30%. The device supports a maximum collector-emitter voltage (VCEO) of -50 V and a continuous collector current (IC) of -100 mA. Power dissipation is rated at 200 mW, with a thermal resistance (RθJA) of 625 °C/W. The DC current transfer ratio (hFE) ranges from 100 to 600 at IC = -1mA and VCE = -5V. The gain-bandwidth product (fT) is typically 250 MHz. Operating and storage temperatures span from -55°C to +150°C.
Feature Summary
- Epitaxial planar die construction for reliable performance
- Integrated single input resistor (R1) simplifies circuit design
- Totally lead-free and fully RoHS compliant
- Halogen and antimony free "Green" device
Applications
- General-purpose switching applications
- Driver circuits for low-power loads
- Logic interface level shifting
Procurement Notes
Verify the specific ordering suffix against official Diodes Incorporated documentation to ensure correct packaging and marking codes. Confirm compliance requirements such as RoHS and halogen-free status directly with the manufacturer or authorized distributors prior to procurement. Ensure the component status is listed as Active for ongoing production needs.
Selection Notes
Select this component when a PNP pre-biased transistor with a 2.2 kΩ base resistor is required. Compare electrical characteristics such as VCEO, IC, and hFE against application demands. Consider the SOT-23 package dimensions and thermal resistance for PCB layout and heat dissipation planning. Verify complementary NPN options if symmetrical pairs are needed.
Part Context
This part belongs to the DDTA (R1-ONLY SERIES) CA family from Diodes Incorporated. It is specifically designed as a PNP pre-biased transistor. Other members in this series include variants with different resistor values, such as DDTA113TCA (1kΩ) and DDTA143TCA (4.7kΩ). The complementary NPN version is available under the DDTC series.
Replacement Considerations
Direct substitutes within the same family include DDTA113TCA-7-F and DDTA143TCA-7-F, differing primarily in the internal resistor value. For complementary functionality, consider the DDTC123TCA-7-F. Always verify pinout compatibility and electrical ratings before substitution.
