Overview
The DDTA115TUA-7-F is a PNP pre-biased transistor from the R1-only series, housed in an SOT-323 package. It features a built-in base resistor (R1) with a nominal value of 100 kOhms 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. Electrical characteristics include a DC current transfer ratio (hFE) ranging from 100 to 600 at IC = -1mA and VCE = -5V, and a gain-bandwidth product (fT) of 250 MHz. Power dissipation is rated at 200 mW, with an operating temperature range spanning from -55°C to +150°C.
Feature Summary
- Epitaxial planar die construction for reliable performance
- Integrated single biasing resistor (R1 only) simplifies circuit design
- Totally lead-free and fully RoHS compliant
- Halogen and antimony free "Green" device
Applications
- General-purpose switching applications
- Driver circuits requiring simplified bias networks
- Automotive electronics (subject to specific qualification requirements)
Procurement Notes
Verify the exact part number suffix against official Diodes Incorporated documentation before procurement. The provided datasheet lists DDTA115TUA-7-F as Active status with a standard marking code P23. Confirm packaging details such as reel size and quantity per reel directly with the manufacturer or authorized distributors to ensure alignment with production requirements.
Selection Notes
Select this component when a PNP pre-biased transistor with a 100 kOhm base resistor is required. Ensure the application voltage does not exceed the -50 V collector-emitter rating and that the load current remains within the -100 mA limit. Consider the thermal resistance of 625 °C/W and power dissipation limits when designing for high ambient temperatures.
Part Context
This component belongs to the DDTA (R1-ONLY SERIES) UA family manufactured by Diodes Incorporated. It is designed as a surface-mount solution in the SOT-323 case, offering a compact alternative to discrete resistor-transistor combinations. The complementary NPN type is available in the DDTC series.
Replacement Considerations
Check for direct substitutes within the same R1-only series, such as variants with different nominal resistor values (e.g., DDTA114TUA for 10kΩ). Verify pinout compatibility and electrical ratings before substituting with components from other manufacturers.
