DDA114YK-7-F

Overview

The DDA114YK-7-F is a dual PNP digital transistor manufactured by Diodes Incorporated, designed for surface-mount applications. It integrates two NPN transistors with built-in biasing resistors in a single SOT-363 package. The device features a maximum collector-emitter voltage of 50V and a continuous collector current of 100mA. It includes an internal resistor ratio of 4.7:1 and meets lead-free and RoHS compliance standards. The component operates within a temperature range up to 150°C and utilizes epitaxial planar construction for reliable performance in small signal switching circuits.

Feature Summary

• Integrates dual PNP transistors with built-in biasing resistors to reduce external component count
• Utilizes SOT-363 surface-mount packaging for compact PCB footprint
• Constructed with epitaxial planar technology for enhanced reliability
• Compliant with lead-free manufacturing and environmental directives

Applications

• General-purpose switching applications in consumer electronics
• Driver circuits for low-power loads requiring pre-biased control
• Logic interface circuits between microcontrollers and peripheral devices

Procurement Notes

Verify the specific suffix 'YK' against the manufacturer's official datasheet to confirm pinout configuration and resistor values, as suffixes often denote mechanical or electrical variations. Ensure the ordering quantity aligns with standard reel sizes if bulk procurement is required. Cross-reference the part number with the latest product change notifications to account for any recent manufacturing site or material updates that may affect compatibility.

Selection Notes

Select this component when a dual PNP configuration with integrated biasing is required to simplify circuit design. The 50V rating and 100mA current capacity suit low-voltage logic interfaces. Compare the internal resistor ratio against alternative models like DDA114EU or DDA114TU to ensure the biasing characteristics match the specific drive requirements of the target application circuit.

Part Context

This part belongs to the DDA114 series of dual PNP digital transistors from Diodes Incorporated. The series offers various packages and resistor ratios to accommodate different space and performance constraints. The DDA114YK variant specifically provides a defined resistor network within the SOT-363 form factor, distinguishing it from single-transistor digital counterparts or other dual configurations in the broader portfolio.

Replacement Considerations

Potential substitutes include DDA114EU-7-F and DDA114TU-7-F, which share the same series family. Verify that the internal resistor ratios and pinouts are compatible before substitution, as these parameters vary across the DDA114 lineup.
