PDTA114EU/SNF

Overview

The Nexperia PDTA114EU is a PNP Resistor-Equipped Transistor (RET) housed in an SC-70 (SOT323) surface-mounted package. It integrates bias resistors R1 and R2, both nominally 10 kΩ, to simplify circuit design. The device supports a maximum collector-emitter voltage of -50 V and an output current capability of -100 mA. Key electrical characteristics include a DC current gain (hFE) of at least 30 at -5 mA, a transition frequency of 180 MHz, and a total power dissipation of 200 mW at 25 °C ambient temperature.

Feature Summary

• Built-in bias resistors reduce component count and simplify circuit design
• Small SOT323 (SC-70) plastic surface-mounted package for space-constrained applications
• High output current capability suitable for general-purpose switching

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details such as tape and reel quantities or cut tape availability. Confirm that the requested variant matches the standard production status rather than a development or obsolete specification. Ensure compliance with RoHS directives and check for any specific automotive qualification requirements if intended for vehicle electronics.

Selection Notes

Select this component when a compact PNP transistor with integrated base biasing is required. The built-in 10 kΩ resistors eliminate external components, reducing assembly costs. Verify that the -50 V collector-emitter voltage rating meets the system's maximum operating voltage. Consider the thermal resistance of 625 K/W in free air for heat dissipation planning in dense PCB layouts.

Part Context

This part belongs to the PDTA114E series of PNP resistor-equipped transistors from Nexperia. It serves as the PNP counterpart to the PDTC114EU NPN RET. The series is designed to replace discrete resistor-transistor combinations, offering a standardized solution for logic interface and switching tasks in small form-factor electronic devices.

Replacement Considerations

The PDTC114EU is the direct NPN complement within the same family. For equivalent PNP functionality with different resistor values, consider other members of the PDTA114 series. Verify pinout compatibility and thermal characteristics before substituting with generic PNP transistors requiring external biasing networks.
