PDTA144EU/ZLX

Overview

The PDTA144EU/ZLX is a PNP Resistor-Equipped Transistor (RET) from the PDTA144E series, housed in an SOT323 (SC-70) surface-mounted package. It integrates a PNP transistor with built-in bias resistors R1 and R2, both nominally 47 kΩ. Key electrical parameters include a collector-emitter voltage (VCEO) of -50 V, an output current (IO) of -100 mA, and a DC current gain (hFE) minimum of 80 at IC = -5 mA. The device features a transition frequency (fT) of 180 MHz and operates within a junction temperature range up to 150 °C.

Feature Summary

• Integrates a PNP transistor with two built-in bias resistors (R1=47kΩ, R2=47kΩ) to reduce component count and simplify circuit design.
• Qualified according to AEC-Q101 standards for use in automotive applications.
• Offers cost-saving alternative capabilities for digital switching loads and IC input control.

Applications

• Digital applications in automotive segments
• Digital applications in industrial segments
• Control of IC inputs
• Switching loads

Procurement Notes

Verify the specific suffix /ZLX against official Nexperia documentation to confirm packaging details, as standard datasheets list packing methods like tape and reel without explicitly defining this suffix's unique handling or quantity constraints. Ensure compliance with AEC-Q101 requirements if deploying in automotive contexts.

Selection Notes

Select the PDTA144EU variant when a very small SC-70 (SOT323) footprint is required. Confirm that the integrated 47 kΩ bias resistors match the target logic interface requirements. Verify thermal dissipation limits for the SOT323 package under expected operating conditions.

Part Context

This component belongs to the PDTA144E series of PNP resistor-equipped transistors. The series includes variants in different packages such as SOT416, SOT883, and SOT23. The EU suffix specifically denotes the SOT323/SC-70 plastic surface-mounted package configuration.

Replacement Considerations

PDTC144EU is the NPN complement within the same family. For direct functional replacement in PNP circuits, verify pinout compatibility and ensure the bias resistor values align with the original design specifications.
