Overview
The PDTA144EQAZ is a PNP Resistor-Equipped Transistor (RET) from the Nexperia PDTA143/114/124/144EQA series, housed in a leadless DFN1010D-3 (SOT1215) package. It features an integrated bias resistor network with R1 and R2 both at 47 kΩ. The device supports a collector-emitter voltage of -50 V and an output current of -100 mA. Key electrical characteristics include a DC current gain (hFE) minimum of 80 at -5 mA/-5 V, a saturation voltage of -150 mV at -10 mA, and a transition frequency of 180 MHz. Total power dissipation reaches 280 mW at 25°C ambient temperature.
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 designs
- AEC-Q101 qualified for automotive applications
- Visible and solderable side pads facilitate Automatic Optical Inspection
Applications
- Digital applications
- Controlling IC inputs
- Switching loads
Procurement Notes
Verify the specific ordering suffix to confirm the reel quantity and tape specifications required for your pick-and-place equipment. Confirm that the DFN1010D-3 footprint matches your PCB layout guidelines. Ensure compliance with RoHS3 standards and check the moisture sensitivity level before assembly processing.
Selection Notes
Select this PNP RET when replacing discrete transistor-resistor combinations to save board space. Verify that the 47 kΩ internal bias values align with your logic drive requirements. Consider the thermal resistance limits if operating near maximum power dissipation thresholds on single-sided FR4 substrates.
Part Context
This component belongs to the PDTA143/114/124/144EQA family of ultra-small surface-mount devices. It serves as a cost-saving alternative to traditional BC847/BC857 series transistors in digital switching circuits. The EQA suffix denotes the specific DFN1010D-3 package variant within the broader EQA series.
Replacement Considerations
PDTC144EQA is the NPN complement within the same series. Direct replacements should match the 47 kΩ bias configuration and DFN1010D-3 package dimensions.
