Overview
The PDTA143EQB is a PNP Resistor-Equipped Transistor (RET) from Nexperia, housed in an ultra-small DFN1110D-3 (SOT8015) leadless package with side-wettable flanks. It features built-in bias resistors R1 and R2, both typically 4.7 kΩ. The device supports a collector-emitter voltage of -50 V and an output current of -100 mA. Total power dissipation reaches 340 mW on a standard FR4 PCB with 35 µm copper. Key electrical characteristics include a DC current gain (hFE) minimum of 30 at -10 mA, a transition frequency of 180 MHz, and a collector-emitter saturation voltage of -100 mV.
Feature Summary
- Built-in bias resistors simplify circuit design by eliminating external input resistors.
- Ultra-thin package height of 0.5 mm optimizes space for compact electronics.
- Side-wettable flanks facilitate Automatic Optical Inspection (AOI) of solder joints.
Applications
- Digital applications
- Controlling IC inputs
- Switching loads
Procurement Notes
Verify the specific ordering code against the manufacturer's official database to ensure correct availability status. Confirm that the DFN1110D-3 package variant matches the required footprint dimensions for the target Printed-Circuit-Board layout. Cross-reference the marking code 'D5' to validate component authenticity upon receipt.
Selection Notes
Select this component when a low-profile PNP switching solution is required. The integrated 4.7 kΩ resistors are suitable for general-purpose logic interfacing. Ensure the thermal resistance requirements align with the 368 K/W junction-to-ambient rating in free air or the reduced value on a PCB.
Part Context
This part belongs to the PDTA143/114/124/144EQB series, which shares the same SOT8015 package but varies in internal resistor values. The PDTA143EQB specifically utilizes matched 4.7 kΩ resistors for R1 and R2, providing a bias ratio of 1. It serves as a cost-saving alternative to discrete transistor and resistor combinations.
Replacement Considerations
Direct replacements within the same series include PDTA114EQB, PDTA124EQB, and PDTA144EQB, which share the identical pinout and package but feature different resistor values. Verify that the alternative resistor ratios meet the specific drive requirements of the application circuit.
