PDTA124EQB-QZ

Overview

The PDTA124EQB-Q is a PNP resistor-equipped transistor from Nexperia, housed in an ultra-small DFN1110D-3 (SOT8015) leadless SMD plastic package with side-wettable flanks. It features built-in bias resistors R1 and R2, both typically 22 kΩ, eliminating the need for external components. The device supports a maximum collector-emitter voltage of -50 V and an output current of -100 mA. It has a minimum DC current gain (hFE) of 60 at VCE = -5 V and IC = -5 mA. Total power dissipation reaches 340 mW on a standard FR4 PCB with 35 µm copper. Qualified under AEC-Q101, it operates within an ambient temperature range of -55 °C to +150 °C.

Feature Summary

• Built-in bias resistors simplify circuit design and reduce component count.
• Ultra-thin package height of 0.5 mm suitable for space-constrained designs.
• Side-wettable flanks enable Automatic Optical Inspection (AOI) of solder joints.
• Automotive grade qualification ensures reliability for automotive applications.

Applications

• Digital switching applications
• Controlling IC inputs
• Switching loads

Procurement Notes

Verify the specific ordering code against the manufacturer's latest catalog to ensure correct packaging and tape-and-reel specifications. Confirm that the DFN1110D-3 footprint matches your PCB layout requirements. Check for any recent product status changes or obsolescence notices directly from Nexperia before finalizing procurement plans.

Selection Notes

Select this component when a compact PNP digital transistor with integrated biasing is required. Ensure the 22 kΩ internal resistor values align with your logic interface voltage levels. Verify that the thermal resistance characteristics fit your board's heat dissipation capabilities, particularly if operating near the upper temperature limits.

Part Context

This part belongs to the PDTA143/114/124/144EQB-Q series, which shares the same SOT8015 package but varies in internal resistor ratios. It serves as a cost-saving alternative to traditional discrete transistor-resistor networks like the BC857-Q series in digital logic circuits.

Replacement Considerations

Direct pin-to-pin replacements within the same series include PDTA143EQB-Q, PDTA114EQB-Q, and PDTA144EQB-Q, provided their respective resistor values are acceptable. NXP's PDTC124EQB-Q is the NPN complement; verify polarity requirements carefully before substitution.
