PDTA144EQC-QZ

Overview

The PDTA144EQC-QZ is a PNP resistor-equipped transistor from the Nexperia PDTA143/114/124/144EQC-Q series, housed in an ultra-small DFN1412D-3 (SOT8009) leadless SMD package with side-wettable flanks. It features built-in bias resistors R1 and R2, both typically 47 kΩ, with a typical ratio of 1. The device supports a collector-emitter voltage (VCEO) of -50 V and a continuous output current (IO) of -100 mA. Key electrical characteristics include a DC current gain (hFE) minimum of 80 at IC = -5 mA and VCE = -5 V, and a transition frequency (fT) of 180 MHz. It operates within an ambient temperature range of -55 °C to +150 °C and is qualified according to AEC-Q101.

Feature Summary

• Built-in bias resistors simplify circuit design and reduce component count.
• Low package height of 0.5 mm suitable for space-constrained applications.
• Side-wettable flanks facilitate Automatic Optical Inspection (AOI) of solder joints.
• Qualified according to AEC-Q101 for automotive applications.

Applications

• Digital applications
• Controlling IC inputs
• Switching loads

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current catalog to confirm availability status and packaging details. Confirm that the DFN1412D-3 package dimensions align with the target PCB footprint requirements. Ensure compliance with RoHS directives and check for any regional supply restrictions or end-of-life notifications prior to finalizing procurement plans.

Selection Notes

Select this component when a compact PNP switching solution with integrated base biasing is required. The 47 kΩ internal resistors are suitable for standard logic interface levels. Consider the thermal resistance values provided in the datasheet for power dissipation calculations under specific PCB copper area conditions. Verify that the -50 V rating meets the system voltage requirements.

Part Context

This part belongs to the PDTA143/114/124/144EQC-Q series, which shares the same SOT8009 package but varies in internal resistor values. The PDTA144 variant specifically utilizes 47 kΩ resistors for both R1 and R2. It serves as a cost-saving alternative to discrete BJT configurations like the BC857-Q series in digital switching roles.

Replacement Considerations

Direct substitutes within the same series include PDTA143EQC-Q, PDTA114EQC-Q, and PDTA124EQC-Q, though their internal resistor values differ. For non-resistor-equipped equivalents, verify pin compatibility and electrical ratings against standard PNP transistors such as the BC857-Q series, ensuring adequate current and voltage margins.
