PDTC144EU,115

Overview

The PDTC144EU,115 is an NPN resistor-equipped transistor (RET) manufactured by Nexperia. It integrates a single NPN bipolar junction transistor with built-in bias resistors R1 and R2 within a compact SOT323 (SC-70) surface-mounted plastic package. The device provides a collector-emitter voltage (VCEO) of 50 V and supports a maximum output current (IO) of 100 mA. The typical input bias resistor (R1) is 47 kΩ, with a standard bias resistor ratio (R2/R1) of 1. Key electrical characteristics include a DC current gain (hFE) minimum of 80 at IC = 5 mA, a transition frequency (fT) of 230 MHz, and a total power dissipation (Ptot) of 200 mW at 25 °C ambient temperature.

Selection Notes

Select the PDTC144EU when a compact NPN switching solution with integrated biasing is required. Ensure the 50 V collector-emitter voltage and 100 mA continuous current ratings align with the load requirements. Verify that the SC-70 (SOT323) package dimensions fit the available PCB footprint. Confirm that the non-automotive qualification status meets the target application standards.

Part Context

This component belongs to the Nexperia PDTC series of NPN resistor-equipped transistors. It serves as the complement to the PDTA144EU PNP variant. The device is designed for general-purpose digital switching and amplification tasks where space efficiency and simplified bias networks are prioritized over high-power handling capabilities.
