Overview
The DDTA144GUA-7-F is a PNP pre-biased small signal surface mount transistor from Diodes Incorporated, housed in an SOT-323 package. It features a built-in biasing resistor (R2) with a nominal value of 47 kOhms. Key electrical ratings include a collector-emitter voltage (VCEO) of -50 V and a continuous collector current (IC) of -100 mA. The device supports a power dissipation of 200 mW and operates within a temperature range of -55°C to +150°C. It offers a minimum DC current gain (hFE) of 68 at IC = -5mA.
Feature Summary
- Integrates a single built-in biasing resistor (R2) for simplified circuit design
- Utilizes epitaxial planar die construction for reliable performance
- Complies with RoHS standards and utilizes 'Green' molding compound
Applications
- General-purpose switching applications
- Driver circuits for low-power loads
- Logic level translation interfaces
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 the required environmental compliance standards, specifically RoHS and lead-free plating specifications, as indicated in the manufacturer's documentation.
Selection Notes
Select this component when a PNP digital transistor with a 47 kOhm internal pull-up resistor is required. Ensure the application voltage does not exceed the -50 V collector-emitter rating and that the thermal management accommodates the 200 mW power dissipation limit in the SOT-323 package.
Part Context
This part belongs to the DDTA144 series of PNP pre-biased transistors. It is functionally complementary to the DDTC144 series NPN types. The 'GUA' designation indicates the SOT-323 package and specific resistor tolerance characteristics defined by the manufacturer.
Replacement Considerations
Direct substitutes include other DDTA144 variants from Diodes Incorporated such as DDTA144EUAQ-7 or DDTA144TKA-7-F, provided they match the SOT-323 footprint and electrical parameters.
