PDTA144EU,115

Overview

The PDTA144EU,115 is a PNP Resistor-Equipped Transistor (RET) manufactured by Nexperia USA Inc. in the SOT323 surface-mount package. It integrates an NPN transistor with built-in bias resistors R1 and R2, both nominally 47 kΩ, resulting in a resistor 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) of at least 80 at IC = -5 mA and VCE = -5 V, a saturation voltage (VCEsat) of -150 mV max at IC = -10 mA, and a transition frequency (fT) of 180 MHz. Total power dissipation is rated at 200 mW at 25 °C ambient temperature.

Feature Summary

• Integrates bias resistors to reduce component count and simplify circuit design
• Qualified for automotive applications under AEC-Q101 standards
• Designed as a cost-saving alternative to discrete BC847/857 series transistors

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging configuration. Confirm that the requested part matches the SOT323 package variant. Cross-reference the full type number with the latest product data sheet to validate current production status and any potential revisions to specifications or marking codes before finalizing procurement orders.

Selection Notes

Select this component when a PNP digital switch with integrated biasing is required in space-constrained designs. Ensure the application voltage does not exceed the -50 V collector-emitter rating. Verify that the required drive current remains within the -100 mA limit. Consider the thermal resistance of the SOT323 package if operating near maximum power dissipation limits in high-temperature environments.

Part Context

This component belongs to the PDTA144E series of PNP resistor-equipped transistors. Other variants in this family include the PDTA144EE (SOT416), PDTA144EM (SOT883), and PDTA144ET (SOT23). All share identical electrical characteristics but differ in physical package dimensions and thermal performance profiles. The EU suffix specifically denotes the SOT323 (SC-70) plastic surface-mounted package.
