Overview
The Nexperia PDTC114EU is an NPN Resistor-Equipped Transistor (RET) housed in a SOT323 (SC-70) surface-mount package. It integrates bias resistors R1 and R2, both nominally 10 kΩ, to simplify circuit design. Key electrical parameters include a collector-emitter voltage (VCEO) of 50 V, an output current capability of 100 mA, and a total power dissipation of 200 mW at 25 °C. The device features a transition frequency of 230 MHz and a DC current gain (hFE) of 30 at 5 mA. Thermal resistance from junction to ambient is 625 K/W in free air.
Feature Summary
- Integrates built-in bias resistors to reduce component count and assembly costs
- Provides simplified circuit design for digital switching applications
- Offers high current capability within a compact SMD plastic package
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 confirm packaging type and reel specifications. Confirm that the non-automotive qualified status aligns with the target application requirements, as this product lacks AEC-Q101 certification. Ensure compatibility with standard reflow or wave soldering footprints provided in the datasheet.
Selection Notes
Select this component when space constraints require a small SC-70 package combined with integrated biasing. It serves as a cost-saving alternative to discrete transistor and resistor combinations. Verify that the 50 V collector-emitter voltage and 100 mA current ratings meet the load requirements. Consider the thermal resistance characteristics if operating near maximum power dissipation limits.
Part Context
The PDTC114EU belongs to Nexperia's family of NPN Resistor-Equipped Transistors (RETs). These devices combine a single NPN bipolar junction transistor with two internal bias resistors. This integration reduces board space and simplifies layout compared to using discrete components. The SOT323 package provides a compact solution for high-density PCB designs.

FAQ
What are the values of the internal bias resistors?
The internal bias resistors R1 (input/base) and R2 are both nominally 10 kΩ.
Is the PDTC114EU automotive qualified?
No, the PDTC114EU is not automotive qualified. Customers requiring automotive qualification should consult Nexperia for suitable alternatives.
What is the pin configuration of the SOT323 package?
Pin 1 is the input (base), Pin 2 is ground (emitter), and Pin 3 is the output (collector).
