PDTA124EU-QF

Overview

The PDTA124EU-QF is a PNP resistor-equipped transistor (RET) manufactured by Nexperia USA Inc. It integrates a single PNP bipolar junction transistor with two built-in bias resistors, R1 and R2, both specified at 22 kΩ. The device is designed for surface-mount installation in the SOT-323 (SC-70) plastic package. Key electrical ratings 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. It features a DC current gain (hFE) of 60 at Ic=5mA and Vce=5V, with a maximum saturation voltage (Vce sat) of 150 mV at Ib=500µA and Ic=10mA. The component is qualified to AEC-Q100 standards for automotive applications.

Feature Summary

• Integrates PNP transistor with dual 22 kΩ bias resistors to simplify circuit design
• Automotive-grade qualification compliant with AEC-Q100 reliability standards
• Compact SOT-323 surface-mount package for high-density PCB layouts

Applications

• General purpose switching and amplification circuits
• Inverter and interface logic circuits
• Circuit driver stages

Procurement Notes

Verify the specific suffix -QF against official Nexperia documentation to confirm exact tape-and-reel packaging specifications and moisture sensitivity level. Ensure the procurement source provides valid traceability records for AEC-Q100 automotive grade compliance. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current production status and availability constraints.

Selection Notes

Select this component when a compact PNP switching solution with integrated base biasing is required. The 22 kΩ internal resistors eliminate external components, reducing board space and assembly costs. Verify that the 50 V collector-emitter voltage rating meets the system's maximum operating voltage requirements. Confirm compatibility with the SOT-323 footprint during the PCB layout phase.

Part Context

This part belongs to the PDTA124 series of pre-biased transistors from Nexperia. It serves as the PNP variant within this family, complementing NPN counterparts like the PDTC124 series. The series is engineered to replace discrete resistor-transistor networks, offering a standardized solution for digital logic interfacing and signal conditioning in consumer and automotive electronics.

Replacement Considerations

Direct functional substitutes within the same package and specification range include the PDTA124E or PDTA124EU variants. Verify pinout compatibility and resistance values before substitution. Alternative packages such as SOT-23 may require schematic redesign.
