PDTA124EQCZ

Overview

The PDTA124EQCZ is a PNP resistor-equipped transistor from the Nexperia PDTA143/114/124/144EQC series, housed in an ultra-small DFN1412D-3 (SOT8009) leadless package with side-wettable flanks. It features built-in bias resistors R1 and R2, both typically 22 kΩ, with a ratio of 1. The device supports a maximum 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 60 at -5 V and -10 mA, a transition frequency (fT) typical of 180 MHz, and a total power dissipation of 360 mW on a 35 µm copper FR4 PCB.

Feature Summary

• Integrates dual bias resistors to simplify circuit design and reduce component count.
• Ultra-low profile package height of 0.5 mm suitable for space-constrained applications.
• Side-wettable flanks facilitate Automatic Optical Inspection (AOI) of solder joints.

Applications

• Digital logic switching applications
• Controlling IC inputs
• Switching loads

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to confirm packaging details and availability status. Confirm that the DFN1412D-3 footprint matches the target PCB layout requirements. Ensure compliance with RoHS directives as specified in the product data sheet before finalizing procurement orders.

Selection Notes

Select this component when a compact PNP digital transistor with equal bias resistors is required. The 22 kΩ internal resistance values are suitable for standard logic interface levels. Consider the thermal resistance characteristics if operating near the maximum junction temperature limits or in high-density board layouts.

Part Context

This part belongs to the PDTA143/114/124/144EQC family, which shares the same SOT8009 package but varies in internal resistor values. The NPN complement for this specific configuration is the PDTC124EQC. The series is designed to replace discrete resistor networks in general-purpose switching circuits.

Replacement Considerations

Direct pin-compatible substitutes within the same series include PDTA143EQC, PDTA114EQC, and PDTA144EQC, provided their respective resistor values meet the circuit requirements. For NPN polarity, the PDTC124EQC serves as the functional complement.
