PDTA114EU/MIF

Overview

The Nexperia PDTA114EU is a PNP Resistor-Equipped Transistor (RET) housed in an SOT323 (SC-70) surface-mounted package. It integrates bias resistors to simplify circuit design and reduce component count. Key electrical parameters include a collector-emitter voltage of -50 V, an output current capability of -100 mA, and a total power dissipation of 200 mW at 25 °C. The built-in input resistor R1 is typically 10 kΩ with a range of 7 to 13 kΩ, while the resistor ratio R2/R1 is nominally 1. The device features a transition frequency of 180 MHz and a DC current gain of 30 at -5 mA.

Feature Summary

• Integrates built-in bias resistors to eliminate external components
• Reduces printed-circuit board space and pick-and-place costs
• Simplifies digital circuit design for switching applications

Applications

• Digital applications in automotive and industrial segments
• Cost-saving alternative for BC847 series in digital circuits
• Controlling IC inputs
• Switching loads

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details such as reel or cut tape quantities. Ensure the requested variant matches the required marking code and manufacturing site specifications defined in the product data sheet before finalizing procurement orders.

Selection Notes

Select this component when a compact PNP solution with integrated biasing is required for digital switching. Verify that the -50 V collector-emitter voltage and -100 mA current ratings align with the target circuit requirements. Consider the SOT323 footprint dimensions for PCB layout compatibility and ensure thermal management meets the 200 mW dissipation limit under operating conditions.

Part Context

The PDTA114EU belongs to the PDTA114E_SER family of NPN/PNP resistor-equipped transistors manufactured by Nexperia. These devices are designed to replace discrete transistor-resistor combinations in digital logic interfaces. The SOT323 package provides a small form factor suitable for space-constrained consumer electronics and industrial control boards requiring efficient signal processing.

Replacement Considerations

The PDTC114EU serves as the NPN complement within the same product family. For direct substitution in existing designs, verify pinout compatibility and ensure the replacement part meets the original voltage and current specifications outlined in the system requirements.
