Overview
The PDTA143XQAZ is a PNP Resistor-Equipped Transistor (RET) housed in a leadless DFN1010D-3 (SOT1215) plastic package. It features an integrated bias resistor network with R1 at 4.7 kΩ and R2 at 10 kΩ. The device supports a collector-emitter voltage of -50 V and an output current capability of -100 mA. Key electrical characteristics include a DC current gain (hFE) of 50 at -10 mA, a collector-emitter saturation voltage of -100 mV at -10 mA, and a transition frequency of 180 MHz. Total power dissipation reaches 280 mW on standard FR4 PCBs.
Feature Summary
- Built-in bias resistors simplify circuit design and reduce component count
- Low profile package height of 0.37 mm suitable for space-constrained applications
- Visible and solderable side pads facilitate Automatic Optical Inspection (AOI)
- Qualified to AEC-Q101 automotive standards
Applications
- Digital logic switching applications
- Controlling IC inputs
- Cost-saving alternative for BC847/BC857 series in digital circuits
Procurement Notes
Verify the specific suffix 'QA' corresponds to the DFN1010D-3 package variant when sourcing. Confirm RoHS compliance and REACH status through official Nexperia channels prior to integration. Ensure ordering documentation matches the exact part number PDTA143XQAZ to avoid confusion with other RET variants in the family.
Selection Notes
Select this component for designs requiring a compact PNP transistor with fixed internal biasing. The 4.7 kΩ input resistor and 10 kΩ emitter-base resistor provide a specific gain ratio suitable for standard logic interfacing. Consider the low thermal resistance on multi-layer PCBs for high-density layouts.
Part Context
This device belongs to the PDTA143X/123J/143Z/114YQA series of 50 V, 100 mA PNP resistor-equipped transistors. All members share the same DFN1010D-3 package and general form factor but differ in their internal R1 and R2 resistor values to accommodate various drive requirements.
Replacement Considerations
PDTC143XQA serves as the NPN complement within the same series. For direct pin-compatible substitution in PNP roles, verify internal resistor tolerances against original design specifications.
