Overview
The DDTA113TUA-7 is a PNP pre-biased transistor from Diodes Incorporated, housed in an SOT-323 package. It features built-in biasing resistors (R1 only) with a nominal value of 1 kΩ. The device supports a maximum collector current of -100 mA and withstands collector-emitter voltages up to -50 V. Electrical characteristics include a minimum DC current gain (hFE) of 100 at IC = -1 mA and VCE = -5 V, and a typical 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 input resistor (R1) simplifies circuit design
- Complementary NPN types available within the DDTC series
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 before procurement. Confirm that the component meets RoHS 3 compliance requirements and matches the requested reel size specifications. Ensure the supplier provides valid traceability data consistent with the manufacturer's standards for automotive or industrial grade parts if applicable.
Selection Notes
Select this component when a compact PNP solution with integrated base resistance is required. Verify that the 1 kΩ internal resistor aligns with the target drive current and logic voltage levels. Consider the thermal resistance and power dissipation limits relative to the expected ambient temperature and board layout conditions.
Part Context
This part belongs to the DDTA R1-only series, which integrates a single biasing resistor into the transistor package. The 'UA' designation indicates the SOT-323 surface-mount case style. This series offers a space-saving alternative to discrete resistor-transistor combinations while maintaining standard electrical parameters for general-purpose use.
Replacement Considerations
Direct replacements must match the PNP polarity, SOT-323 package, and 1 kΩ internal resistor value. Verify that any substitute maintains the same -50 V voltage rating and -100 mA current capability. Check for equivalent thermal characteristics and hFE ranges to ensure circuit compatibility.
