The PDTA114TU-QX is a PNP resistor-equipped transistor (RET) from Nexperia, designed for general-purpose switching and amplification. It integrates a single PNP transistor with built-in bias resistors to simplify circuit design and reduce component count. The device operates within a collector-emitter voltage range of up to 50 V and supports a continuous collector current of 100 mA. It features a typical input resistance of 10 kOhms and is housed in an SOT-323 (SC-70) surface-mount package. Qualified under AEC-Q101 standards, it ensures reliability for automotive applications.
Verify the specific suffix -QX against official Nexperia documentation to confirm AEC-Q101 qualification status and exact electrical tolerances. Ensure the ordering part number matches the required SOT-323 package variant. Cross-reference the manufacturer's datasheet for any recent product change notices or longevity program updates before finalizing procurement plans.
Select this component when a compact PNP switching solution with integrated biasing is required for space-constrained designs. The SOT-323 package offers a small footprint suitable for high-density PCB layouts. Verify that the 50 V collector-emitter voltage and 100 mA current ratings align with the target application's load requirements and operating conditions.
This part belongs to the Nexperia PDTA114 series of PNP resistor-equipped transistors. The series includes variants with different resistor values and packages, such as the PDTA114TT in SOT-23 and PDTA114EU in SOT-323. The -QX suffix typically denotes automotive-grade qualification, distinguishing it from standard commercial versions within the same functional family.
Direct substitutes include other PDTA114 series variants like PDTA114EU or PDTA114YT if package or resistor tolerance differences are acceptable. Verify pinout compatibility and thermal characteristics when replacing with non-Nexperia equivalents.
