This datasheet provides specifications, package outlines, and ordering information for Nexperia PDTC144W series NPN resistor‑equipped transistors.
The PDTC144W series are NPN transistors with built‑in bias resistors (R1 = 47 kΩ, R2 = 22 kΩ) that simplify circuit design and reduce component count. The document lists electrical limits, thermal characteristics, and mechanical dimensions for each package type.
Key features include built‑in bias resistors, a collector‑emitter voltage rating of 50 V, and a maximum output current of 100 mA. Recommended soldering method is reflow soldering, and the series is suitable for general‑purpose switching, amplification, inverter and interface circuits.
