PDTC144EQBZ

Overview

The PDTC144EQB is a 50 V, 100 mA NPN Resistor-Equipped Transistor (RET) from Nexperia. It integrates bias resistors R1 and R2, both typically 47 kΩ, into an ultra-small DFN1110D-3 (SOT8015) leadless package with side-wettable flanks. The device features a collector-emitter voltage of 50 V, output current capability of 100 mA, and total power dissipation up to 340 mW at 25 °C on a standard footprint. Operating junction temperature ranges from -55 °C to +150 °C.

Feature Summary

• Integrates built-in bias resistors to simplify circuit design and reduce component count.
• Ultra-thin package height of 0.5 mm suitable for space-constrained applications.
• Side-wettable flanks facilitate Automatic Optical Inspection (AOI) of solder joints.

Applications

• Digital switching and amplification circuits
• Controlling IC inputs
• Switching loads

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to confirm packaging details and reel specifications. Ensure compliance with RoHS directives and check for any recent Product Change Notices that may affect assembly or testing sites before finalizing procurement orders.

Selection Notes

Select this component when a compact NPN transistor with integrated base biasing is required. The 47 kΩ resistor values are suitable for general-purpose digital logic interfacing. Consider the DFN1110D-3 package dimensions and thermal resistance characteristics relative to the PCB copper area for adequate heat dissipation during operation.

Part Context

This part belongs to the PDTC143/114/124/144EQB series, which shares the same SOT8015 package but varies in internal resistor values. The PNP complement for this specific device is the PDTA144EQB. All members of this family offer identical electrical ratings and physical dimensions, differing only in the integrated resistance ratios.

Replacement Considerations

Direct functional substitutes within the same package include other PDTC144 variants such as PDTC144ET or PDTC144WM, provided the pinout and resistor tolerances match the design requirements. Verify that alternative packages like SOT-23 or DFN1006-3 fit the available board space.
