DDTA115TUA-7-F

Overview

The DDTA115TUA-7-F is a PNP pre-biased transistor from the R1-only series, housed in an SOT323 surface-mount package. It integrates a single internal biasing resistor 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

• Integrates a single built-in biasing resistor (R1 only) for simplified circuit design
• Utilizes epitaxial planar die construction for reliable performance
• Compliant with RoHS standards and free from halogen and antimony

Applications

• General-purpose switching applications requiring integrated base biasing
• Driver circuits for low-power loads within specified voltage limits
• Automotive electronics compatible with IATF 16949 certified manufacturing processes

Procurement Notes

Verify component authenticity by checking the marking code against official Diodes Incorporated documentation. Confirm compliance status through manufacturer declarations regarding RoHS and REACH directives. Ensure ordering suffixes match specific packaging requirements such as reel size and tape width. Validate date codes and lot traceability prior to integration into production workflows.

Selection Notes

Select this component when a PNP configuration with a 100 kOhm base resistor is required. Verify that the -50 V voltage rating and -100 mA current capacity align with load specifications. Consider the SOT323 package dimensions for PCB layout constraints. Evaluate thermal resistance values if operating near maximum power dissipation limits.

Part Context

This part belongs to the DDTA (R1-ONLY SERIES) UA family manufactured by Diodes Incorporated. It shares the SOT323 case style with other variants in the series but differs in its specific integrated resistor value. The 'UA' designation indicates the specific package type and pinout configuration used across this product line.

Replacement Considerations

Direct substitutes within the same series include DDTA113TUA-7-F (1kΩ), DDTA114TUA-7-F (10kΩ), and DDTA125TUA-7-F (200kΩ). Complementary NPN types are available in the DDTC series. Verify electrical parameters and package compatibility before substituting.
