PDTC143XQBZ

Overview

The PDTC143XQB is a 50 V, 100 mA NPN Resistor-Equipped Transistor (RET) manufactured by Nexperia. It integrates bias resistors R1 and R2 with nominal values of 4.7 kΩ and 10 kΩ respectively. The device utilizes a DFN1110D-3 (SOT8015) leadless surface-mount package measuring 1.1 x 1.0 x 0.48 mm with side-wettable flanks. Key electrical parameters include a collector-emitter voltage (VCEO) of 50 V, an output current (IO) of 100 mA, and a transition frequency (fT) of 230 MHz. The component operates within an ambient temperature range of -55 °C to +150 °C.

Feature Summary

• Integrates built-in bias resistors to simplify circuit design and reduce component count.
• Features a low profile package height of 0.5 mm suitable for space-constrained applications.
• Designed for Automatic Optical Inspection (AOI) compatibility via side-wettable flanks.

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to ensure correct resistor configurations and packaging variants. Confirm that the DFN1110D-3 footprint matches the target PCB layout requirements. Cross-reference the marking code E7 with incoming inspection standards to validate authenticity and traceability during the procurement process.

Selection Notes

Select this component when a compact NPN switching solution with integrated base biasing is required. The 4.7 kΩ input resistor value suits standard digital interface levels. Ensure the application voltage does not exceed the 50 V collector-emitter rating. Consider the thermal resistance characteristics if operating in high-power density environments or restricted airflow conditions.

Part Context

This part belongs to the Nexperia PDTC143 series of Resistor-Equipped Transistors. It serves as the NPN complement to the PDTA143XQB PNP variant. The series provides a cost-effective alternative to discrete transistor and resistor combinations, specifically targeting digital applications where board space and assembly costs are critical design constraints.

Replacement Considerations

Direct functional substitutes within the same family include PDTC123JQB, PDTC143ZQB, PDTC114YQB, and PDTC124XQB. These alternatives share the SOT8015 package but differ in internal resistor values. Verify pinout compatibility and electrical ratings before substitution.
