PDTC143TU,115

Overview

The PDTC143TU,115 is an NPN resistor-equipped transistor (RET) from the PDTC143T series manufactured by Nexperia. It integrates a single bias resistor (R1 = 4.7 kΩ) with no parallel resistor (R2 open). The device is housed in the SOT323 (SC-70) surface-mount package. Key electrical parameters include a collector-emitter voltage (VCEO) of -50 V and a DC output current (IO) of -100 mA. The typical DC current gain (hFE) is specified at 200 under standard test conditions.

Feature Summary

• Built-in bias resistors simplify circuit design
• Reduction of component count
• Reduced pick and place costs

Applications

• General purpose switching and amplification
• Inverter and interface circuits
• Circuit applications

Procurement Notes

Verify the specific ordering suffix to confirm the tape-and-reel packaging configuration intended for automated assembly processes. Confirm RoHS compliance status through official Nexperia documentation before finalizing procurement specifications. Ensure the selected variant matches the required manufacturing origin indicated in the product overview table.

Selection Notes

Select this component when a compact NPN switching solution with integrated base biasing is required. The SOT323 package offers space efficiency for high-density PCB layouts. Verify that the 4.7 kΩ internal resistor value aligns with the target drive current requirements for the specific application logic levels.

Part Context

This part belongs to the PDTC143T series of NPN resistor-equipped transistors. It serves as the complement to the PDTA143TU PNP variant. The series provides standardized biasing configurations to replace discrete resistor networks in general-purpose electronic designs.

Replacement Considerations

Direct functional substitutes within the same series include the PDTC143TT (SOT23 package) and PDTC143TK (SOT346 package), provided the footprint change is acceptable.
