DDA143TUQ-13-F

Overview

The DDA143TUQ-13-F is a PNP pre-biased dual transistor manufactured by Diodes Incorporated. It features an epitaxial planar die construction and integrates two biasing resistors within a single SOT363 package. The device is AEC-Q101 qualified for automotive applications and operates with a collector-emitter breakdown voltage of -50V and a continuous collector current of -100mA. Nominal input resistance (R1) is 4.7kΩ, with a DC current gain (hFE) ranging from 100 to 600 at IC = -1mA. Power dissipation is rated at 200mW, and the operating temperature range spans from -55°C to +150°C.

Feature Summary

• Integrated dual PNP transistors with built-in biasing resistors in a compact surface-mount package
• AEC-Q101 qualified and PPAP capable for automotive supply chain requirements
• Totally lead-free and fully RoHS compliant with halogen and antimony-free green molding compound

Applications

• Automotive electronic systems requiring specific change control protocols
• General-purpose switching and driver circuits utilizing dual PNP configurations
• Embedded logic interface applications replacing discrete resistor-transistor networks

Procurement Notes

Verify component authenticity through authorized distribution channels to ensure compliance with automotive quality standards. Confirm that the ordering suffix corresponds to the required packaging quantity and reel specifications. Validate that the supplier provides traceability documentation consistent with IATF 16949 manufacturing processes. Ensure storage conditions adhere to moisture sensitivity level 1 guidelines prior to soldering.

Selection Notes

Select this component when a dual PNP configuration with integrated biasing is required in a minimal footprint. The 4.7kΩ nominal input resistance suits standard logic interface voltages. Verify that the -50V collector-emitter breakdown voltage meets circuit requirements. Consider the 200mW power dissipation limit and thermal resistance characteristics during PCB layout planning.

Part Context

This part belongs to the DDA series of pre-biased dual transistors offered by Diodes Incorporated. The 'U' designation indicates automotive-grade qualification under AEC-Q101 standards. The 'Q' suffix denotes the automotive variant, while '13-F' specifies the 10,000-unit tape and reel packaging format. It complements the DDC series which offers NPN configurations.

Replacement Considerations

Direct functional substitutes include other DDA143TU variants such as DDA143TU-7-F, though packaging quantities differ. For automotive-specific replacements, verify AEC-Q101 qualification status. Non-automotive equivalents may lack the required change control documentation. Always validate pinout compatibility and electrical parameters before substitution.
