DDA143TUQ-7-F

Overview

The DDA143TUQ-7-F is a PNP pre-biased dual transistor manufactured by Diodes Incorporated, housed in an SOT363 surface-mount package. It features built-in biasing resistors with nominal values of R1 = 4.7 kΩ and R2 = 4.7 kΩ. The device supports a maximum collector-emitter voltage (VCEO) of -50 V and a continuous collector current of -100 mA. Power dissipation is rated at 200 mW, with an operating temperature range from -55°C to +150°C. This component is AEC-Q101 qualified for automotive applications.

Feature Summary

• AEC-Q101 qualified for high reliability automotive applications
• PPAP capable and manufactured in IATF 16949 certified facilities
• Totally lead-free and fully RoHS compliant construction

Applications

• Automotive electronic circuits requiring specific change control
• General-purpose digital switching applications
• Driver circuits for low-power loads

Procurement Notes

Verify the complete part number including the 'Q' suffix to ensure compliance with automotive standards. Confirm that the required packaging quantity matches the available reel sizes. Check for any recent Product Change Notifications regarding manufacturing sites or materials before finalizing procurement orders.

Selection Notes

Select this component when automotive qualification and PPAP capability are mandatory requirements. Ensure the circuit design accommodates the -50 V supply voltage limit and -100 mA output current constraints. Verify that the 4.7 kΩ input resistor configuration aligns with the intended logic drive levels and switching speed requirements.

Part Context

This part belongs to the DDA(XXXX)U series of PNP pre-biased dual transistors. It serves as the automotive-grade equivalent to the standard DDA143TU-7-F model. Both share identical electrical characteristics and physical dimensions but differ in quality assurance and manufacturing traceability protocols.

Replacement Considerations

The standard DDA143TU-7-F is electrically compatible but lacks automotive qualification. For non-automotive replacements, verify if the ADA114EUQ is suitable based on resistance values.
