PDTA124XQBZ

Overview

The PDTA124XQB is a PNP resistor-equipped transistor (RET) from Nexperia, housed in the DFN1110D-3 (SOT8015) leadless surface-mount package. It integrates bias resistors with values of 22 kΩ for R1 and 47 kΩ for R2. The device supports a maximum collector-emitter voltage (VCEO) of -50 V and an output current (IO) of -100 mA. Key electrical characteristics include a DC current gain (hFE) minimum of 80 at -5 mA, a transition frequency (fT) typical of 180 MHz, and a total power dissipation of 340 mW on a standard FR4 PCB.

Feature Summary

• Integrates built-in bias resistors to simplify circuit design and reduce component count.
• Features an ultra-small DFN1110D-3 package with side-wettable flanks for improved solder joint inspection.
• Offers low profile height suitable for space-constrained applications.

Applications

• Digital logic applications
• Controlling IC inputs
• Switching loads

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to ensure correct packaging and tape-and-reel specifications. Confirm that the DFN1110D-3 footprint matches the target PCB design guidelines provided by Nexperia. Check for any recent product status changes or obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when a compact PNP switching solution with integrated base biasing is required. The 22 kΩ input resistor value determines the drive current requirements compared to discrete transistors. Ensure the application voltage does not exceed the -50 V collector-emitter rating and consider the thermal resistance characteristics for high-duty cycle operations.

Part Context

This part belongs to the PDTA143X/123J/143Z/114Y/124XQB series, which shares the same SOT8015 package but varies in internal resistor ratios. It serves as a cost-saving alternative to traditional discrete transistor pairs like the BC857 series in digital switching circuits, offering reduced assembly complexity and board space.

Replacement Considerations

Direct substitutes within the same series include PDTA143XQB, PDTA123JQB, PDTA143ZQB, and PDTA114YQB, though each has distinct resistor values. For NPN equivalents, consult the PDTC124XQB datasheet. Verify pinout compatibility and thermal performance when replacing discrete BJT configurations.
