The PDTA124EU-QX is a PNP resistor-equipped transistor (RET) manufactured by Nexperia USA Inc. It integrates a single PNP bipolar junction transistor with two internal bias resistors, R1 and R2, both specified at 22 kΩ. The device is designed for surface-mount installation in the SOT-323 (SC-70) package. Key electrical parameters include a maximum collector-emitter voltage (VCEO) of 50 V, a continuous collector current (Ic) of 100 mA, and a total power dissipation (Pd) of 200 mW. The component meets AEC-Q100 automotive qualification standards.
Verify the specific suffix -QX against official Nexperia documentation to confirm it denotes the correct tape-and-reel packaging format and quantity. Ensure the part number matches the required SOT-323 package variant and that the automotive grade designation aligns with project specifications before finalizing procurement orders.
Select this component when a compact PNP switching solution with integrated base and emitter biasing is required. The 22 kΩ resistor values are suitable for standard logic interface levels. Verify that the 50 V breakdown voltage and 100 mA current rating exceed the maximum operational loads in the target application environment.
This part belongs to the PDTA124 series of pre-biased transistors from Nexperia. These devices replace discrete transistor-resistor networks, offering cost savings in pick-and-place manufacturing. The EU suffix typically indicates the SOT-323 package configuration within this product family.
Direct functional equivalents include the PDTA123ETVL and PDTC124E series components, provided the polarity and resistance values match the design requirements. Cross-reference specific pinouts and thermal characteristics with the original datasheet before substitution.
