Overview
The PDTC143XQC is a 50 V, 100 mA NPN Resistor-Equipped Transistor (RET) from Nexperia. It integrates bias resistors R1 (4.7 kΩ typ) and R2 (10 kΩ typ) with a ratio of 2.13 within an ultra-small DFN1412D-3 (SOT8009) leadless package featuring side-wettable flanks. The device supports a collector-emitter voltage of 50 V and continuous output current of 100 mA. Key electrical characteristics include a DC current gain (hFE) of 50 at IC=10 mA, a transition frequency (fT) of 230 MHz, and a total power dissipation of 360 mW on a standard FR4 PCB. Operating temperatures range from -55 °C to +150 °C.
Feature Summary
- Integrates built-in bias resistors to simplify circuit design and reduce component count.
- Ultra-small DFN1412D-3 package with side-wettable flanks for improved solder joint inspection.
- Low profile height of 0.5 mm suitable for space-constrained applications.
Applications
- Digital logic switching
- Controlling IC inputs
- Switching loads
Procurement Notes
Verify the specific suffix 'QC' corresponds to the DFN1412D-3 package variant during sourcing. Confirm RoHS compliance status through official Nexperia documentation or authorized distributors before procurement. Ensure the ordering code matches the required resistor values for the intended design.
Selection Notes
Select this component when a compact NPN transistor with integrated base biasing is required. The DFN1412D-3 package offers a smaller footprint compared to traditional SOT-23 packages. Verify that the 4.7 kΩ input resistor value aligns with the driving source impedance and desired switching speed requirements.
Part Context
This part belongs to the Nexperia PDTC143X/123J/143Z/114Y/124XQC series, which provides various resistor combinations in the same DFN1412D-3 package. The PNP complement for this specific configuration is PDTA143XQC. The series is designed as a cost-saving alternative to discrete BC847 series transistors in digital applications.
Replacement Considerations
Direct replacements within the same package include PDTC123JQC, PDTC143ZQC, PDTC114YQC, and PDTC124XQC, provided their internal resistor values are compatible with the circuit design. The PNP equivalent is PDTA143XQC.
