DDA114YU-7-F

Overview

The DDA114YU-7-F is a PNP pre-biased dual transistor manufactured by Diodes Incorporated, housed in an SOT363 surface-mount package. It integrates two independent PNP transistors with built-in biasing resistors (R1 = 10 kΩ, R2 = 47 kΩ) to simplify circuit design and reduce component count. The device features epitaxial planar die construction and operates within a supply voltage range of -50 V. It supports a continuous collector current of -100 mA and dissipates up to 200 mW of power. The unit is fully RoHS compliant, halogen-free, and suitable for automated assembly processes.

Feature Summary

• Integrates dual PNP transistors with fixed internal biasing resistors to minimize external components
• Utilizes epitaxial planar die construction for reliable switching performance
• Manufactured using lead-free, halogen-free, and antimony-free green materials

Applications

• General-purpose switching applications requiring compact dual-transistor solutions
• Driver circuits for logic-level interface and signal buffering
• Automotive electronics utilizing AEC-Q101 qualified variants

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation before procurement. The standard -7-F suffix indicates a 3,000-unit reel packing quantity. Confirm that the selected variant aligns with the required resistor values and package dimensions for the target PCB layout. Ensure compliance with environmental directives such as RoHS 3 if applicable to the final product specifications.

Selection Notes

Select this component when a dual PNP configuration with integrated base and emitter resistors is required. The DDA114YU variant specifically provides 10 kΩ and 47 kΩ resistors. Compare electrical characteristics such as DC current gain and saturation voltage against alternative discrete transistor pairs to ensure compatibility with the intended load and drive requirements. Verify thermal resistance limits under maximum ambient temperature conditions.

Part Context

This part belongs to the DDA series of pre-biased dual transistors from Diodes Incorporated. The series offers various resistor combinations and configurations to accommodate different logic families and drive currents. Complementary NPN types are available in the DDC series. The SOT363 package allows for high-density mounting on printed circuit boards compared to larger through-hole alternatives.

Replacement Considerations

The datasheet identifies the DDA114YUQ-7-F variant as Not Recommended for New Design (NRND). For new designs requiring this specific configuration, the ADA114YUQ is suggested as the designated replacement part.
