PDTC143ZQCZ

Overview

The PDTC143ZQC is a 50 V, 100 mA NPN Resistor-Equipped Transistor (RET) from Nexperia. It integrates bias resistors into an ultra-small DFN1412D-3 (SOT8009) leadless package with side-wettable flanks. The device features a typical input resistor R1 of 4.7 kΩ and a resistor ratio R2/R1 of 10. Key electrical limits include a collector-emitter voltage (VCEO) of 50 V, continuous output current (IO) of 100 mA, and total power dissipation up to 360 mW at 25 °C on a standard 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 supports Automatic Optical Inspection (AOI).
• Low profile height of 0.5 mm suitable for space-constrained surface-mount applications.

Applications

• Digital logic switching circuits
• Controlling IC inputs
• Switching loads

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details and reel specifications. Ensure compliance with RoHS directives and REACH regulations as stated in the product data sheet. Confirm that the DFN1412D-3 footprint matches the target PCB layout requirements before finalizing procurement orders.

Selection Notes

Select this component when a compact NPN switch with integrated base biasing is required. The 4.7 kΩ input resistor value determines the drive current requirements compared to discrete transistors. Verify thermal performance using the provided derating curves if operating above 25 °C ambient temperature or on PCBs with lower copper weight than the standard test conditions.

Part Context

This part belongs to the Nexperia PDTC143X/123J/143Z/114Y/124XQC series, which shares the same SOT8009 package but varies in internal resistor values. The PNP complement for this specific configuration is PDTA143ZQC. The series is designed as a cost-saving alternative to traditional BC847 series transistors in digital applications.

Replacement Considerations

Direct functional substitutes within the same package and resistor configuration are limited. The PDTA143ZQC serves as the PNP equivalent. Other members of the QC series (PDTC143XQC, PDTC123JQC, etc.) share the package but have different resistor ratios and must be evaluated for circuit compatibility.
