Overview
The DDTA114GUA-7-F is a PNP pre-biased small signal surface mount transistor from Diodes Incorporated, housed in an SOT-323 package. It features an epitaxial planar die construction and includes a built-in biasing resistor R2 with a nominal value of 10 kΩ. The device supports a maximum collector current of -100 mA and withstands collector-emitter voltages up to -50 V. Electrical characteristics include a DC current transfer ratio (hFE) minimum of 30 at IC = -5 mA, 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
- Integrates a single built-in biasing resistor (R2 only) to simplify circuit design
- Utilizes epitaxial planar die construction for reliable performance
- Available in a compact SOT-323 surface mount case
Applications
- General-purpose switching applications requiring integrated biasing
- Driver circuits for low-power loads
- Logic interface buffering
Procurement Notes
Verify the specific ordering suffix '-7-F' corresponds to the tape and reel packaging configuration containing 3000 units per reel. Confirm that the component meets RoHS compliance standards and utilizes lead-free plating with a matte tin finish annealed over an Alloy 42 leadframe. Ensure the 'Green' molding compound specification is required for the intended application environment.
Selection Notes
Select this component when a PNP digital transistor with a 10 kΩ emitter resistor is required. Compare against complementary NPN types within the DDTC series if an NPN configuration is needed instead. Verify that the SOT-323 package dimensions and thermal resistance characteristics align with the PCB layout and power dissipation constraints of the target design.
Part Context
This part belongs to the DDTA (R2-only series) UA family manufactured by Diodes Incorporated. It is specifically designed as a pre-biased small signal transistor where only the emitter resistor is integrated internally. The series offers various resistor values, with the 114 variant providing a 10 kΩ nominal resistance.
Replacement Considerations
Complementary NPN versions are available in the DDTC series. Other variants within the same package may offer different resistor values such as 22 kΩ or 47 kΩ.
