PDTA143EQB-QZ

Overview

The PDTA143EQB-Q is a PNP Resistor-Equipped Transistor (RET) from Nexperia, housed in an ultra-small DFN1110D-3 (SOT8015) leadless surface-mount package with side-wettable flanks. It features built-in bias resistors R1 and R2, both nominally 4.7 kΩ. The device supports a maximum collector-emitter voltage of -50 V and a continuous output current of -100 mA. Key electrical characteristics include a DC current gain (hFE) minimum of 30 at -10 mA and -5 V, a transition frequency of 180 MHz, and a total power dissipation of 340 mW on a standard FR4 PCB. The component is qualified to AEC-Q101 standards for automotive applications.

Feature Summary

• Built-in bias resistors simplify circuit design by eliminating the need for external input resistors.
• Ultra-small DFN1110D-3 package with side-wettable flanks facilitates Automatic Optical Inspection (AOI).
• Low profile of 0.5 mm height reduces overall board space requirements.
• Qualified according to AEC-Q101 for use in demanding automotive environments.

Applications

• Digital switching and amplification circuits
• Controlling IC inputs
• Switching loads
• Cost-saving alternative to BC857-Q series in digital applications

Procurement Notes

Verify the specific ordering code against the manufacturer's latest documentation to ensure correct package and marking configuration. Confirm that the DFN1110D-3 footprint matches the intended PCB layout, paying attention to the side-wettable flank requirements for reliable soldering. Ensure compliance with RoHS directives and check for any recent Product Change Notifications (PCN) regarding assembly sites or materials before finalizing procurement plans.

Selection Notes

Select this component when a compact PNP solution with integrated biasing is required for space-constrained designs. The 4.7 kΩ resistor values are suitable for general-purpose logic interfacing. Consider the thermal resistance characteristics if operating near the maximum junction temperature limits. Verify that the -50 V rating meets the system's voltage headroom requirements and that the 100 mA current capability aligns with the load specifications.

Part Context

This part belongs to the PDTA143/114/124/144EQB-Q series, which offers various resistor combinations within the same DFN1110D-3 package. The NPN complement for this specific variant is the PDTC143EQB-Q. The series is designed to replace discrete resistor-transistor networks, reducing component count and assembly costs in modern electronic devices.

Replacement Considerations

The NPN equivalent is PDTC143EQB-Q. Other series members with different resistor values include PDTA114EQB-Q, PDTA124EQB-Q, and PDTA144EQB-Q. Direct pin-compatible replacements must maintain the DFN1110D-3 package and similar electrical ratings.
